Whilst the theoretical description of electrode processes is mainly concerned with thermodynamic functions such as energy, enthalpy, entropy and volume, very few experimental determinations of these important quantities have been made. This paper describes the theoretical significance of experimental values of the temperature and pressure coefficients of electrode processes. Particular importance is attached to (1) the equilibrium surface excess volumes and entropies and (2) the real and ideal activation parameters associated with charge‐transfer reactions.
