WebThe differential form of Fick’s second law is the basic equation for the study of isothermal diffusion. Derivation of Fick’s Second Law: Consider an elemental slab of thickness Ax along the diffusion distance x. Let the slab X- section be perpendicular to x and its area be unity. The volume of the slab is then ∆x x 1 = ∆x. WebApr 23, 2024 · Fick's law of diffusion (equation 7.2.1) describes all the factors that influence the transfer of gas (or flow, V) across a membrane.
