WebThe Nernst equation is E is equal to E zero minus .0592 over n, times the log of Q. Well at equilibrium, at equilibrium E is equal to zero, so we plug that in. So we have zero is equal to the standard cell potential, E zero, minus .0592 over n, times the log of Q. But at equilibrium, remember, Q is equal to K.
