The Frumkin correction is added to this equation to account for diffuse layer effects. In a non-acid-base type of titration, this equation serves as the basis of Gran plots. This equation can be used to calculate the peaks of a duck-shaped graph in a certain technique. This equation is used to calculate y-coordinates on Pourbaix diagrams. When using this equation at room temperature, one coefficient equals approximately (*) 0.0592. A generalization of this equation becomes approximately equal to the Tafel equation when the magnitude of the overpotential is sufficiently large. At equilibrium, the Butler–Volmer equation reduces to this equation, which has a coefficient of RT over zF times the natural log (10[1])of the reaction quotient. For 10 points, name this equation used to determine the reduction potential in an electrochemical reaction. ■END■
