FUELS, ENERGY CHANGES AND RATES OF REACTION: Entropy, Activation Energy, Energy Profiles And The Collision Theory.
Entropy is a measure of the disorder of a system. The entropy of a gas is higher than the entropy of a solid, because there are more ways of arranging molecules in a gas, and so there is more disorder.
