Abstract
An explicit expression for the exchange current density in terms of work function of the metal surface, surface potential of the reactants and products, and solvation energies was derived. The usefulness of the expression was demonstrated for a ferric/ferrous reaction whose i0 values have been reported for a variety of electrodes using experimental data and theoretical calculations.
