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:
or
where
is the
electrode current density,
is the
stoichiometric number,
is the
charge number of the electrode reaction,
is the
Faraday constant,
is the
interfacial concentration,
is the
bulk concentration,
is the
transport number of species B, and
is the
charge number of species B.
