Item
Type(s)/Category(s)	EmmoTerm

Term

EmmoTerm
Comment	Deviation of the potential of an electrode from its equilibrium value required to cause a given current to flow through the electrode. [en] Difference between the electrode potential with current flow, and the electrode potential without current flow, i.e. the equilibrium potential. [en] Overpotential is positive for oxidation reactions and negative for reduction reactions. [en] Overpotential is the extra potential, in relation to the equilibrium value, required to cause a given electric current to flow through the electrode. [en]
