The change in Gibbs free energy (DeltaG) 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 asystem at constant temperature and pressure will be: DeltaG_("system")=DeltaH_("system")-TDeltaS_("system") At constant temperature and pressure: DeltaG_("system")lt0 (Spontaneous) DeltaG_("system")=0 (equilibrium) DeltaG_("system")gt0 (non-spontaneous) Free energy is related to the equilibrium constant as: DeltaG^(@)=2.303RTlog_(10)K_(e). Q. A reaction has positive values of DeltaH and DeltaS. From this you can deduce that the reaction:

Answer» MUST be SPONTANEOUS at any TEMPERATURE. cannot be spontaneous at any temperature. Will be spontaneous only at low temperature will be spontaneous only at high temperature. Answer :D
