Preferred Label : mass transfer coefficient;
Detailed label : mass transfer coefficient in electrochemistry;
IUPAC definition : 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: \[k_{{d}}
\frac{j\ \nu }{n\ F\ (c_{{e}}- c_{0})}\] or \[k_{{d}} \frac{j\ \nu \ (1- t_{{B}}\
n\ \nu {-1}\ z_{{B}} {-1})}{n\ F\ (c_{{e}}- c_{0})}\] 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,
t B is the transport number of species B, and z B is the charge number of species
B.;
