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"#.
