1.	Delta_(r) G^(@)= - RT " In K. For the same reaction at the same temperature using " K_(p) and K_(p) " the values "Delta _(r)G^(@) "are found to be different . Why ?
Answer» Solution :The numerical value of equilibrium constant depends upon the standard state chosen for expressing concentrations or pressures. In CASE of pressures, the standard state chosen is 1 bar wheras in case of concentrations, standard state chosen is `1" MOL "L^(-1). " HENCE " , Delta_(r) G^(@)` VALUES are DIFFERENT.
