Preferred Label : heterogeneous diffusion rate constant;
Detailed label : heterogeneous diffusion rate constant in electrochemistry;
IUPAC definition : Defined by the equation: \[k_{{d}} \frac{I_{{l}}}{n\ F\ c\ A}\] where the limiting
current Il is assumed to be due to the diffusion species of concentration c and of
diffusion coefficient D. n is the charge number of the cell reaction written so that
the stoichiometric coefficient of this species is unity. A is usually taken as the
geometric area of the electrode, and F is the Faraday constant.;
