Input (English): This statement can be derived by taking the natural log of a one-electron redox reaction written using Boltzmann factors. This equation can be generalized by considering multiple ions flowing across a cell membrane, a situation described by Hodgkin, Katz and Goldman. A term containing the gas constant times temperature over Faraday's constant is subtracted from the standard half-cell reduction potential in this equation. Typically applied to Galvanic cells, it is named for a German chemist. For 10 points, name this electrochemical equation which determines the equilibrium reduction potential of a half-cell.
Output (English): Science
