That equation requires there be no surface states when considering semiconductors in solutions, and predicts that the gradient of transfer is half of that for metals in the overpotential limit.
The potential of the outer Helmholtz plane is important to a modified version of this equation. That equation requires there be no surface states when considering semiconductors in solutions, and predicts that the gradient of transfer is half of that for metals in the overpotential limit. The Tafel equation comes from this equation, as does another equation that involves electrode surface area. Yet another equation derived from this one is applied to (*) cell membranes. On one side of this equation, the natural gas constant is multiplied by temperature times natural logarithm reaction quotient divided by Faraday's constant. Its variants include the Butler-Volmer and Goldman equation and it is used to determine the reduction potential of an electrochemical cell. For 10 points, name this equation central to electrochemistry.
