Sum of its enthalpy, Chemistry

What is basically Gibb''s free energy change?

Ans) The energy associated with a chemical reaction that can be used to do work.  The free energy of a system is the sum of its enthalpy (H) plus the product of the temperature (Kelvin) and the entropy (S) of the system...          
               DeltaG=Delta H - T Delta S

Gibb''''s free energy is the useful work done by the system.....  G=H-TS.....If G is negative,the  rxn is spontaneous   &   if  G is positive , the rxn is non-spontaneous
