Nernst equation

Meaning

Noun

• An electrochemical equation that relates the reduction potential of a half-cell (or the total voltage, i.e. the electromotive force, of the full cell) at any point in time to the standard electrode potential, temperature, activity, and reaction quotient of the underlying reactions and species used.

Origin

• Named after the German physical chemist Walther Nernst, who formulated it.
