Entropy Changes in Chemical Reactions.

Entropy Changes in Chemical Reactions. Because entropy is a state function, the property is what it is regardless of pathway, the entropy change for a given reaction can be calculated by taking the difference between the standard entropy values of products and those of the reactants.
