The magic of chemistry comes with thrills and excitement, flashy reactions and fireworks, with colour and sound. It is not bonding and structure that grab the imagination, but spectacle and change. Here is the topic that tells the real story of chemistry. Chemical change, more than anything, happens in a crowded environment. Factors of importance are the state of aggregation, material concentration, temperature and pressure, collectively known as thermodynamic conditions. Students of chemistry, even at the elementary level, should be familiar with thermodynamic models of chemical reactivity. For a concise revision refer to . A brief summary follows.
