Gibbs Free Energy

                      It is a thermodynamic property. It was defined by Josiah Willard Gibbs. It is denoted as G. Gibbs free energy is the energy associated with a chemical reaction that can be used to do work. The process will occur spontaneously at constant temperature and pressure. G is defined as,
                                 G  =  H - TS
H  -->  Enthalpy
T  -->  Temperature ( Kelvin )
S  -->  Entropy
