About this deal

An example of a very simple spontaneous process is that of a melting ice cube. Energy is transferred from the room to the ice cube, causing it to change from the solid to the liquid state.

If this is the first time you use this feature, you will be asked to authorise Cambridge Core to connect with your account.Many useful chemical reactions involve burning fuels to release energy. These reactions heat our homes, power our cars and generate lots of the electricity that we use. Unique unified approach helps the reader to see the connections between different ideas and concepts across the traditional divisions of chemistry Chemical reactions also tend to proceed in such a way as to increase the total entropy of the system, measured by the entropy change (\(\Delta S\)) between reactants and products. How can you tell if a certain reaction shows an increase or a decrease in entropy? The states of the reactants and produces provide certain clues. The general cases below illustrate entropy at the molecular level.

Why Do Chemicals React? Kinetics and Thermodynamics Why Do Chemicals React? Kinetics and Thermodynamics

So far I’ve only done a few chapters of volume 1. I really intended to work through it in its totality at one stage, but I realised that I should use my time before university to learn things other than physics. Thermodynamics is responsible for determining whether chemical reactions ‘go’ or not and that reactions themselves are not ‘alive’, so cannot ‘decide’. Informal peer and self assessment is inherent throughout the group discussions (that promote listening, discussion and development of coherent ideas), the role play (that requires team working and cooperation), the demonstrations and the plenaries (when teacher questioning and review are essential).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. I proceeded to read the first two chapters, and was able to easily follow the physics-based reasoning. I therefore listed it on my UCAS personal statement, with the full intention of reading the whole thing before the interview. However, after the first few chapters, the material becomes rather dense (especially with the focus on MO theory). I did endure through it, and made some notes along the way. The notes are quite verbose, because the book itself is quite succinct anyway. I wasn’t asked anything about the book in my interview, which I suppose is fortunate because I would have probably struggled.
