This equation's namesake also names the "Heat Theorem," an alternative to the Third Law of Thermodynamics.  
This equation's namesake also names the "Heat Theorem," an alternative to the Third Law of Thermodynamics.  This equation can be generalized to a simplification of the Tafel equation, known as the Butler-Volmer equation, and it can be generalized through an equation used to determine the reversal potential across a cell membrane, the Goldman Equation. In this equation, the gas constant times temperature over n times Faraday's Constant is multiplied by the natural log of Q. For 10 points, identify this fundamental equation of electrochemistry, named after a German chemist.
