Along with Planck, this equation's namesake denotes a molar flux equation, which reduces to this equation if the net flux is zero. In the chord-conductance equation, the term subtracted from the electric field is obtained using this equation. It can be derived by relating the chemical potential to a ratio written in terms of Boltzmann factors, as well as by noting the relation between Gibbs free energy, entropy, and cell potential. For 10 points, name this equation, which can be used to find the equilibrium reduction potential for a half cell.
