An enthalpy term and an entropy term.

Explanation:

DeltaG^@=DeltaH^@ -TDeltaS^@

The Gibbs free energy is the single, unequivocal criterion for the spontaneity of chemical change. Negative values of DeltaG denote a "spontaneous reaction".

DeltaG may also be related to the equilibrium constant, K_"eq" by the equation:

DeltaG^@ =-RTlnK_"eq".
