12.8: Standard Potentials and Equilibrium Constants

12.8: Standard Potentials and Equilibrium Constants. We can calculate K eq values from standard potentials if we by relating the previous expression for Gibbs free energy to the one we’ve learned this chapter. We know from Ch. 9 that:  G° =-RTlnK eq We know from this chapter that:
