The heterogeneous diffusion rate constant defined for the case of the limiting current. A more general definition in terms of the electrode current densities is: kd=j νn F (ce−c0) or kd=j ν (1−tB n ν−1 zB−1)n F (ce−c0) where j is the electrode current density, ν is the stoichiometric number, n is the charge number of the electrode reaction, F is the Faraday constant, ce is the interfacial concentration, c0 is the bulk concentration, tB is the transport number of species B, and zB is the charge number of species B.
