[In electrochemistry], defined by the equation kd = i1/nFcA where the limiting current i1 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. 1, record 1, English, - heterogeneous%20diffusion%20rate%20constant

[En électrochimie], définie par l'équation: kd = il/nFcA pour laquelle on fait l'hypothèse que le courant limite, Il, est dû à l'espèce diffusante de concentration, c, et de coefficient de diffusion, D. n est le nombre de charges de la réaction de cellule écrite d'une façon telle que le coefficient stœchiométrique de cette espèce est égal à l'unité. On considère généralement que A est la superficie géométrique de l'électrode et que F est la constante de Faraday. 1, record 1, French, - constante%20de%20vitesse%20de%20diffusion%20h%C3%A9t%C3%A9rog%C3%A8ne
