WebOct 5, 2014 · It is dependent on temperature (and material). Fick's second law holds because the diffusivity, D, is constant with respect to depth, x, and time, t, so it is treated as a constant in the equation. ∂ c x ∂ t = ∂ ∂ x ( D ∂ c x ∂ x) = D ( ∂ 2 c x ∂ x 2) Fick's second law of diffusion applies to non steady state diffusion, which ...
