### Re: using entropy

Entropy is a measure of disorder and is used when finding Gibb's free energy instead of just ∆H and the heat of a reaction. Entropy is used a lot in the law of thermodynamics as one of the laws says that the universe tends towards disorder and chaos, meaning a higher entropy.
