Entropy change in chemical reactions
- The entropy change for a chemical reaction among pure, crystalline substances is zero at the absolute zero K by the Third law of thermodynamics.
- Therefore, the entropy change of a chemical reaction at 298 K is simply the difference between the sum of the standard entropies of the products and the sum of the standard entropies of the reactants.
- The entropy changes at other temperatures
