WebFick's second law: Consider the case when there is diffusion at the front and rear surfaces of an incremental planar volume. Fick's second law states that "the rate of accumulation (or depletion) of concentration within the volume is proportional to the local curvature of the concentration gradient". The second law of diffusion is a linear ... WebFick's second law builds a relationship between concentration and diffusion flux under an unsteady state. Fick’s second law equation indicates the variable is changing with time, or the time to diffuse increases with the square of distance x. The equation for Fick's second law is as follows: d ρ d t = D d 2 ρ d x 2.
