Factors That Affect the Chemical Reaction Rate

Its useful to be able to predict whether an action will affect the rate at which a chemical reaction proceeds. Several factors can influence the chemical reaction rate. In general, a factor that increases the number of collisions between particles will increase the reaction rate and a factor that decreases the number of collisions between particles will decrease the chemical reaction rate. Concentration of Reactants A higher concentration of reactants leads to more effective collisions per unit time, which leads to an increased reaction rate (except for zero-order reactions.) Similarly, a higher concentration of products tends to be associated with a lower reaction rate. Use the partial pressure of reactants in a gaseous state as a measure of their concentration. Temperature Usually, an increase in temperature is accompanied by an increase in the reaction rate. Temperature is a measure of the kinetic energy of a system, so higher temperature implies higher average kinetic energy of molecules and more collisions per unit time. A general rule for most (not all) chemical reactions is that the rate at which the reaction proceeds will approximately double for each 10-degree Celsius increase in temperature. Once the temperature reaches a certain point, some of the chemical species may be altered (e.g., denaturing of proteins) and the chemical reaction will slow or stop. Medium or State of Matter The rate of a chemical reaction depends on the medium in which the reaction occurs. It may make a difference whether a medium is aqueous or organic; polar or nonpolar; or liquid, solid, or gaseous. Reactions involving liquids and especially solids depend on the available surface area. For solids, the shape and size of the reactants make a big difference in the reaction rate. Presence of Catalysts and Competitors Catalysts (e.g., enzymes) lower the activation energy of a chemical reaction and increase the rate of a chemical reaction without being consumed in the process. Catalysts work by increasing the frequency of collisions between reactants, altering the orientation of reactants so that more collisions are effective, reducing intramolecular bonding within reactant molecules, or donating electron density to the reactants. The presence of a catalyst helps a reaction proceed more quickly to equilibrium. Aside from catalysts, other chemical species can affect a reaction. The number of hydrogen ions (the pH of aqueous solutions) can alter a reaction rate. Other chemical species may compete for a reactant or alter orientation, bonding, electron density, etc., thereby decreasing the rate of a reaction. Pressure Increasing the pressure of a reaction improves the likelihood reactants will interact with each other, thus increasing the rate of the reaction. As you would expect, this factor is important for reactions involving gases, and not a significant factor with liquids and solids. Mixing Mixing reactants increases their ability to interact, thus increasing the rate of a chemical reaction. Summary of Factors The chart below is a summary of the main factors that influence the reaction rate. There is typically a maximum effect, after which changing a factor will have no effect or will slow a reaction. For example, increasing temperature past a certain point may denature reactants or cause them to undergo a completely different chemical reaction. Factor Affect on Reaction Rate temperature increasing temperature increases reaction rate pressure increasing pressure increases reaction rate concentration in a solution, increasing the amount of reactants increases the reaction rate state of matter gases react more readily than liquids, which react more readily than solids catalysts a catalyst lowers activation energy, increasing reaction rate mixing mixing reactants improves reaction rate

Significantly, I will not approach aging as a state (documented by the photographic image) but as a process of growth (that is, of subject construction, and of shaping, adapting subjectivity to new parameters). In this dynamics of change and becoming rather than a destructive agent, time is conceived of as a formative category and a source of creativity.

Manufacturing Technology Journal Advanced -Myassignmenthelp.Com

Question: Discuss About The Manufacturing Technology Journal Advanced? Answer: Introduction The main purpose of the report is to understand the different concepts of additive manufacturing or 3D printing, which is a new technology that is being increasingly used in different industrial sectors. This emerging psychology has brought a revolution in the manufacturing industry. 3D printing or additive manufacturing has offered a new paradigm in manufacturing industry by enabling the feature of customized printing. 3D printing, which is also known as additive manufacturing, offers a speedy and cost effective solution, thus adding a competitive advantage in the market. The report discusses the working principle of 3D printing or additive manufacturing. The report further discusses whether the 3D printing is suitable for high or low volume of production. With the increasing popularity and usage of 3D printing or additive manufacturing, the traditional manufacturing process has taken a backseat (Weller, et al., 2015). The report discusses the role of 3D printing in turning the trad itional manufacturing obsolete. The increase in the growth and popularity of 3D printing is largely because of reduced labour and cost requirement (Campbell, et al., 2011). The various functionalities of 3D printing are elaborated in the following paragraphs. 3D printing/Additive Manufacturing 3D printing is also known as additive manufacturing as the process includes development of a prototype by adding a preferred material or mould layer by layer. In simple words, 3D printing is a process of joining the different layers of materials, to develop a 3D model or structure, and hence the name. 3D printing makes use of a digital model as a guide to print a 3D structure if a particular design. The layer by layer addition is very quick for low volume production and therefore it is used in developing the concept models. Additive manufacturing is a process of manufacturing that combines a large number of minuscule layers in creating a particular product. This process is however very quick. The term 3D printing is used to refer the different types of additive manufacturing and hence it is known by the name of additive manufacturing as well (Chua Leong, 2014). Additive manufacturing differs from subtractive manufacturing through a large extent, as a model is built up by adding the materials layer by layer. The simple process of adding layers by layers in development of a model helps in manufacturing complex products with ease. Additive manufacturing therefore, refers to a process of manufacturing a three dimensional design or data by subsequent addition of layer of different material. Additive manufacturing is therefore used as a synonym of 3D printing. However, the term additive manufacturing is more appropriate to consider as it describes the manufacturing technique. This helps in distinguishing 3D printing from subtractive manufacturing (Weller, et al., 2015). 3D printing in high and low volume of production The process of 3D printing is most suited for low volume of production. The process of additive manufacturing makes even the complex-manufacturing simple. However, the process of 3D printing is economics and cost effective only for low volume production. Furthermore, the layer by layer addition of materials to develop a set structure is a time consuming work in case of large volume of production. One of the main constraints for small manufacturers is the budget allocated for a particular task (Mueller, 2012). 3D printing eliminates any extra cost by reducing the number of labours and time required for completion of a project. However, in case of a large volume of production, it becomes extremely difficult to follow this process due to a time constraint. 3D manufacturing optimizes the low volumes production as the traditional manufacturing methods such as injection modelling is very expensive. Therefore, it can be said that 3D printing is a growing opportunity for low volume of production. 3D printing is increasing used in modelling of engineering and architectural works and finds extensive usage in chemical industry and in building medical implants as well. 3D manufacturing however has a capability and potential to be used in high volume of production as well (Kietzmann, et al., 2015). Situations in which 3D printing is valuable 3D printing was initially developed for rapid prototyping. However, in course of time, it found its application in rapid manufacturing as well. 3D printing has various applications in different business sectors including engineering, food, chemistry and medicine (Suchubert , et al., 2014). The medical application of 3D printing is rapidly expanding and has numerous application in healthcare sector. It is used in developing hearing devices, dentistry, surgery and medical devices. This incurs a high value in medical applications. The different application of 3D printing in medicine includes customized implants and prosthetics (Ventola, 2014). Furthermore, researches are laid on application of 3D printing in bioprinting. Apart from this, 3D printing can be potentially used for bringing revolutionary changes in the field of healthcare such as in development of surgical cuttings and drill guides, orthopaedic implants and prosthetics. Therefore, it can be said that 3D printing is most valuable for its application in the healthcare (Gibson, et al., 2014). Apart from this, the other applications of 3D printing include structuring complex components for aerospace, automotive and chemical industry. 3D printing has varied application in research industry as well. Researchers use 3D printing in crafting prototypes required for the research. 3D printing has further revolutionized the architecture industry as well. 3D printed houses and building nowadays have become a trend. Therefore, it can be seen that 3D printing has a wide range of application across the different business sectors. Forecast by investment firms With the growing demand and use of 3D printing, the investment firms are keen on integrating 3D printing or additive manufacturing in their business. A 2010 Ganter report identified the 3D printing technology as a transformational technology in the Trigger phase hype cycle (Campbell, et al., 2011). The recent reports and This can trigger the investment firms in taking active interest in this technology to enhance their business processes. This is the reason for which the 3D printing has emerged over broad range of industries in recent times. Researches prove that different companies have capitalized on the products made by integration of 3D printing by taking a manufacturing based approach. 3D printing in making traditional manufacturing obsolete With the increasing use of 3D printing, the traditional manufacturing has taken a back seat. This is because, the technology of 3D printing provides a cost effective solution in a much less time. The process of 3D printing provides some unique advantages over traditional manufacturing (Vaezi, et al., 2013). One of the major advantages of additive manufacturing is that it prevents wastage of materials, as it is a resource efficient approach. The traditional manufacturing methods such as injection mould on a contrary require extra material to fill the mould. Therefore, it is observed that the additive manufacturing process produce much less waste than traditional manufacturing (Lipson Kurman, 2013). Furthermore, the additive manufacturing helps in easy prototype production as it has become very easy to develop a prototype in hours with the help of 3D printing. Therefore, the 3D printing is preferably used for prototyping instead of traditional manufacturing (Berman, 2012). Furthermore , the 3D printing technology allows higher degree of customization of products and development of complex structure that is not possible with traditional manufacturing. Additive manufacturing promotes development of innovative products and increases the speed of marketing new products. The process of traditional manufacturing is complex and time consuming and therefore, there is a high possibility of traditional manufacturing getting obsolete with the advent of additive manufacturing. Furthermore, in the prototypes developed with traditional manufacturing, it becomes very difficult to rework on the same. On the other hand, rework on the prototypes developed with 3D printing is much easier as in case of a rework, a new prototype can be built quite efficiently and in a very less time. Although the use of 3D printing is preferable in rapid prototyping, it is not suitable for high volume manufacturing. This is because, the layer by layer addition of materials becomes very difficult and time consuming for high volume of production. Conclusion Therefore, from the above discussion, it can be concluded that 3D printing is a technology that has varied usage in the different industrial sectors. The different application of 3D printing is discussed in the report. The report evaluates whether additive manufacturing is suited for high and low volume of production. 3D printing is more suitable for low volume of production due to its speed and efficiency. The report further discusses the possibility of 3D printing or additive manufacturing in making the traditional manufacturing obsolete. Although there is an increasing use of additive manufacturing in prototyping, it will take a huge amount of time to replace the process of traditional manufacturing completely. Recommendation 3D printing should be increasingly used in prototyping as it provides a cost effective solution. Small and medium sized manufacturers can integrate the process of 3D printing in their business in order to save time and money in prototyping. Further studies and researchers are required in order to completely replace the process of traditional manufacturing by 3D printing References Berman, B., 2012. 3-D printing: The new industrial revolution.

Argumentative Essay on Government Banning Video Games Essay Example

Argumentative Essay on Government Banning Video Games Essay Example Argumentative Essay on Government Banning Video Games Essay Argumentative Essay on Government Banning Video Games Essay Essay Topic: Argumentative Should the Government Ban the Sale of Violent Video Games? â€Å"Too many of the video games marketed to our children teach them all of the wrong lessons and values† (Whitehead 108). These are the words from the Illinois governor Rod Blagojevich who is trying to outlaw the sale of violent video games. This issue has been around for a while and the government is looking into it. They say that violent behavior by small children is an effect of the violence seen in the video games. Many people have supported the actions taken by the government but others see it as a waste of resources. There are a number of reasons the government should not get involved in banning the sale of video games. Parents should be responsible and take care of their children. Proponents claim that that the government should ban violent video games for a number of reasons. They claim that research has shown that violent video games affect young people in both short and long term. This leads children to criminal and antisocial behavior. Parents don’t actually know how violent video games actually are and use them to keep their children busy while they are minding their own business so there is no parental supervision. The government has taken interest in this since many people believe that the role of the government is to protect society and its citizens from damaging society as a whole. However, it would be wrong for the government to take steps in censoring violent video games since it is something that is impossible to do. The government would require a great deal of money to stop the sales of video games. Yet, it won’t stop anything since retailers could then move their sales to the internet where the government won’t be able to perform so well. All the money invested would then be a waste. Many people against the law say that the government should spend the money in something more useful or needed. It would be a waste of resources to try and control the sales when internet is so accessible to everyone and can provide access to anything. Furthermore, violent acts by children cannot be attributed to video games; there are a lot of things that come into play. Many known researchers have found that there is no link between violent behavior and video games. The most recent study was performed by Patrick Kierkegaard at the University of Essex, England; it suggested that there is no link between violent video games and violent behavior. Kierkegaard explained that the effect seems to be the exact opposite and one might argue that video game usage has reduced real violence (Kierkegaard). He also states that it is possible for certain types of video game to affect emotions, views, behavior, and attitudes, however, so can books. These can also lead to violent behavior on those already predisposed to violence. Nevertheless, many of the video games that are found to be violent are not created for children. These games are written for adults and have an effective rating system implemented on them. One such rating system is the Entertainment Software Rating Board (ESRB). It was created by the major video game manufacturers due to pressure applied by concerned groups about the content on video games. Many game companies now submit their products for rating by the ESRB. A number of factors are considered when rating games. They include the amount of violence, sex, profane language and substance abuse. The ESRB then gives an age recommendation and a content description to the games submitted. This rating system allows parents to know what each game contains and allows them to make responsible decisions for their children. As evidence shows, it would not be wise for the government to get involved in this. Parents play a large role in development of their children. They are the ones that go and buy the games for the children without paying attention to the safety measures already in place. I have been a video game player for many years and have played every kind of game. Yet, the teachings I received since I was a kid are still in me and I have never had the urge to be violent due to a video game. Parents should take responsibility for their children and the government should not be responsible for the actions of the parents. Dafoe Whitehead, Barbara.
