Why Chemical Reactions Happen

Product Information

In a chemical reaction, chemical bonds between atoms are broken and made, so the atoms get rearranged into new substances. A colour change – If the new chemicals are a different colour from the original chemicals, there will be a colour change.

Fortunately, this reaction is nonspontaneous at normal temperatures and pressures, it is a highly endothermic reaction. However, nitrogen monoxide is capable of being produced at very high temperatures, and this reaction has been observed to occur as a result of lightning strikes. Informal written style with the emphasis on understanding through models and real examples keeps the text accessible and relevant The driving force for a reaction is a very important concept. No chemical reaction can happen without it. If we are not sure whether a reaction is feasible or not, one of the first things we should do is to look for a plausible driving force.By observing chemical reactions, we are able to understand and explain how the natural world works. Chemical reactions turn food into fuel for your body, make fireworks explode, cause food to change when it is cooked, make soap remove grime, and much more.

Prior to becoming Head of Department, I was for many years our Director of Teaching with overall responsibility for the delivery of the undergraduate chemistry course. My own teaching is in the area of introductory physical and theoretical chemistry e.g. thermodynamics, high-resolution spectroscopy and elementary group theory. Research

University Associate Professor

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.

If you carry out an investigation you will record evidence of any changes. The evidence you record is called data and it may be quantitative or qualitative. An acquaintance of mine was once having trouble wrapping their head around the Binomial Theorem. As someone who likes maths (and likes teaching people maths), I wanted to come up with an intuitive explanation. CT1 Financial Mathematics For a given substance, the entropy of the liquid state is greater than the entropy of the solid state. Likewise, the entropy of the gas is greater than the entropy of the liquid. Therefore, entropy increases in processes in which solid or liquid reactants form gaseous products. Entropy also increases when solid reactants form liquid products.

These types of demonstrations encourage people to ask questions and may lead them into science-related careers. Physical changes, such as melting, boiling and dissolving, do not make new chemicals. They are usually easy to reverse. newcommand{\vecs}[1]{\overset { \scriptstyle \rightharpoonup} {\mathbf{#1}}}\) \( \newcommand{\vecd}[1]{\overset{-\!-\!\rightharpoonup}{\vphantom{a}\smash{#1}}} \)\(\newcommand{\id}{\mathrm{id}}\) \( \newcommand{\Span}{\mathrm{span}}\) \( \newcommand{\kernel}{\mathrm{null}\,}\) \( \newcommand{\range}{\mathrm{range}\,}\) \( \newcommand{\RealPart}{\mathrm{Re}}\) \( \newcommand{\ImaginaryPart}{\mathrm{Im}}\) \( \newcommand{\Argument}{\mathrm{Arg}}\) \( \newcommand{\norm}[1]{\| #1 \|}\) \( \newcommand{\inner}[2]{\langle #1, #2 \rangle}\) \( \newcommand{\Span}{\mathrm{span}}\) \(\newcommand{\id}{\mathrm{id}}\) \( \newcommand{\Span}{\mathrm{span}}\) \( \newcommand{\kernel}{\mathrm{null}\,}\) \( \newcommand{\range}{\mathrm{range}\,}\) \( \newcommand{\RealPart}{\mathrm{Re}}\) \( \newcommand{\ImaginaryPart}{\mathrm{Im}}\) \( \newcommand{\Argument}{\mathrm{Arg}}\) \( \newcommand{\norm}[1]{\| #1 \|}\) \( \newcommand{\inner}[2]{\langle #1, #2 \rangle}\) \( \newcommand{\Span}{\mathrm{span}}\)\(\newcommand{\AA}{\unicode[.8,0]{x212B}}\)
