TRODUCTION Chemical processes occur spontaneously when they lower the free energy of the system. The free energy at constant temperature and ressure is the Gibbs free energy, AG, which is defined as follows: AG = AH - TAS where AG is the change in free energy of the system, AH is the change in enthalpy of the system and AS is the change in entropy of the system AG, the change in free energy, must be less than zero for...
