The change in Gibbs free energy of the system along provides a criterion for the spontaneity of a process at constant temperature and pressure. A change in the free energy of a sytem at constant temperature and pressure will be: DeltaG_("system") = DeltaH_("system") - T DeltaS_("system") For a spontaneous reaction DeltaG , equilibrium constant K and E_("cell")^(0) will be respectively:

For a spontaneous process, in a reaction
