Bonjour, dans une correction d'un QCM on nous dit que jd = - D x k x (1-sigma) x S x (gradient de concentration) / épaisseur de la membrane 

 

je ne comprend pas pourquoi on rajoute l'épaisseur de la membrane dans cette formule car ce n'est pas mentionner dans la formule du cour.

 

Merci d'avance pour vos réponses.
