Because I was considering a career as an actuary, I thought it might be interesting to take one of the exams to get a better understanding of the material.

Entropy generally increases in reactions in which the total number of product molecules is greater than the total number of reactant molecules.These types of demonstrations encourage people to ask questions and may lead them into science-related careers.

For a given substance, the entropy of the liquid state is greater than the entropy of the solid state. He doesn’t sacrifice any of his characteristic charm, while still explaining the counterintuitive theory. The determining factors for spontaneity of a reaction depend on both the enthalpy and entropy changes that occur for the system. I decided to choose CT1, because I was already confident with the CT3 content, so I thought that I would learn more from studying CT1.In January 2015, when I was examining the reading lists for Cambridge and reading example personal statements for Natural Sciences, I noticed that a common denominator was the book Why Chemical Reactions Happen, by Keeler and Wothers.

By tackling the most central ideas in chemistry, Why Chemical Reactions Happen provides the reader with all the tools and concepts needed to think like a chemist. The text takes a unified approach to the subject, avoiding the traditional divisions of physical, inorganic and organic chemistry and so helps the reader to develop a real overview of chemical processes.

7.4: Why Do Chemical Reactions Occur? Free Energy

I wasn’t asked anything about the book in my interview, which I suppose is fortunate because I would have probably struggled. This combination of a decrease in energy and an increase in entropy means that combustion reactions occur spontaneously. The entropy change is unknown (but likely not zero) because there are equal numbers of molecules on both sides of the equation, and all are gases.
