Choose the incorrect statement: Gibb's Free Energy is defined as: GH-TS OF AG<0, the process is spontaneous. Of AG > 0, the process is nonspontaneous. The Second Law of Thermodynamics says that all spontaneous processes produce an increases in the entropy of the universe. Of AG-0, the process is spontaneous.

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...
