The change in Gibbs free energy of the system alone provides a criterion for the spontaneity of a process at constant temperature and pressure. A change in the free energy of a system at constant temperature and pressure will be :
`DeltaG_("system")=DeltaH_("system")-T DeltaS_(system")`
For a system in equilibrium, `DeltaG=0`, under conditions of contant....

For a system in equilibrium, DeltaG=0 , under conditions of constant

For a system in equilibrium, DeltaG=0 , under conditions of constant

For a system in equilibrium Delta G= 0 under conditions of constant:

For a system in equilibrium, DeltaG = 0 under conditions of constant :

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:
