Standard free energy of the reaction is defined as the energy of products - energy of reactants
Delta G(rxn) = Delta G(products) - Delta G(reactants)
The value of K or equilibrium reaction defines as the [Products]/[Reactants] at the time of course of reaction.
Delta G = -RTln(K)
So, with Delta G value we can calculate the equilibrium constant where R is universal gas constant with a fixed value of 8.314 J/K.mol
