![Chemical energy is released or absorbed from reactions in various forms. The
most easily measurable form of energy comes in the form of heat, or enthalpy
Thesenthalpy of a reaction can be calculated from the heats of formation of the
substances involved in the reaction:
AHAH; (products)-AH; (reactants)
Entropy change, AS", is a measure of the number of energetically equivalent
microstates Introduced into the system during the reaction. The degree of
spontaneity of a reaction is represented by the Gibbs free energy, AG. The
Gibbs free energy depends on both the enthalpy and entropy changes that take
place during the reaction:
