[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

[In electroanalytical chemistry], a quantity whose expression includes a current, whose value is characteristic of a charge-transfer process and the experimental conditions under which it is investigated, and whose nature depends on the technique that is employed. Some typical response constants are the diffusion current constant in polarography, the voltammetric constant in linear-sweep voltammetry, and the chronopotentiometric constant in chronopotentiometry. 1, record 3, English, - diffusion%20current%20constant
