The enthalpy change for a reaction can be calculated using the formation enthalpies of the products and reactants. It would be possible to use formation entropy values to calculate the entropy change for a reaction in a similar manner; however, this is not done in practice. Describe the procedure in calculating entropy change of reactions that is used instead.
