Hess's Law Practice Problems to Boost Your Understanding of Chemical Reactions - postfix
A: Enthalpy change is the total energy change of a reaction, while entropy change is a measure of the disorder or randomness of a system. Both changes are important in understanding chemical reactions, but they are calculated differently.
A: Yes, Hess's Law can be used to predict the spontaneity of a reaction by calculating the total enthalpy change. If the total enthalpy change is negative, the reaction is spontaneous; if it's positive, the reaction is non-spontaneous.
