mass transfer coefficient in electrochemistry

mass transfer coefficient

in electrochemistry

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:

$Math - e$

or

$Math - e$

where $Math - symbol$ is the electrode current density, $Math - symbol$ is the stoichiometric number, $Math - symbol$ is the charge number of the electrode reaction, $Math - symbol$ is the Faraday constant, $Math - symbol$ is the interfacial concentration, $Math - symbol$ is the bulk concentration, $Math - symbol$ is the transport number of species B, and $Math - symbol$ is the charge number of species B.
