potential value), real activation energy A (determined at a constant overpotential), and the so called formal acti-
vation energy
(calculated at a constant electrode potential vs. an arbitrarily chosen reference electrode). The obtained equations include only the parameters of the studied reaction and no characteristics of the reaction
occurring on the reference electrode. The type of the
dependence on the electrode potential is established. Conditions are found, under which the real and formal activation energies of the electrochemical reactions can
simultaneously remain constant in the given temperature range and it becomes possible to use them in the inte-
gral forms of the Arrhenius equation.
