Web3 2. Theoretical background Diffusion can be described by Fick’s second law of diffusion in terms of concentration,C, time, t, and space, x, ∂C ∂t = D ∂2C ∂x2, (1) where D is the diffusion coefﬁcient [2]. Knowing ∂C/∂t and ∂2C/∂x2, one can easily solve for D.In order to determine reliable values, it is necessary to smooth the concentration WebDerivation 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. Let, J / x = Rate of change of flux with distance, and. C / t = Rate of change of concentration per unit volume in the ...

WebFick’s Laws of Diffusion [Click Here for Sample Questions] Fick’s law of diffusion was derived by Adolf Fick in the early 19th century. He explained the law of diffusion as when the molar flux due to diffusion is proportionate to the concentration gradient, the absorption rate of change is a point in space which is proportional to the second derivative of … WebFick's Law. Fick's Law describes passive movement molecules down its concentration gradient. Flux (J) (molecules per unit time) = (C 1 - C 2) · (Area ·Permeability coefficient) / Thickness.
