WebThe equation that relates free energy and potential is given by delta G is equal to negative nFE. Delta G is the instantaneous difference in free energy between the reactants and the products and refers to the number of electrons that are transferred in the redox reaction. WebJul 27, 2014 · If you want to calculate ΔG under non-standard conditions, you need to use the equation ΔG = ΔG0 +RT lnQ where Q is the ratio of concentrations (or activities) of the products divided by the reactants. Under standard conditions Q=1 and ΔG = ΔG0. Under equilibrium conditions, Q=K and ΔG = 0 so ΔG0 = −RT lnK.
