For 10 points, identify this equation from electrochemistry named for a German.
The man who lends his name to this also named an alternative to the Third Law of the Thermodynamics, his "Heat Theorem". One form of it sums outward and inward-flowing species on a cell membrane based on charge, also known as the Goldman equation. Other terms in this equation include the constant RT/F, with F being Faraday's constant, and it is used the ratio of equilibrium ionic concentrations to determine reduction potentials.
