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. WebFeb 2, 2016 · Substituting the values of the constants into Equation \(\ref{Eq3}\) with \(T = 298\, K\) and converting to base-10 logarithms give the relationship of the actual cell …
