Butler-Volmer equation is an activation controlled reaction, the one for which the rate of reaction is controlled solely by the rate of the electrochemical charge transfer process, which is in turn an activation-controlled process. This gives rise to kinetics that are described by the Butler-Volmer equation:
where io is exchange current density, η is overpotential (η = E - Eo), n is number of electrons, αA is anodic transfer coefficient, and αC is cathodic transfer coefficient
