Ficks law of diffusion
WebFick proposed laws governing the diffusion of atoms and molecules, which can be applied to the diffusion processes in metals and alloys. He proposed two laws, the first for steady-state condition and unidirectional flow of atoms and the second law which deals with time dependence of concentration gradient; and the flow of atoms in all directions.

WebFick's Law can be written as an equation which can be used to calculate the rate of diffusion; Rate = P x A x ((C 1 - C 2) T). Where P = A permeability constant that is a quantitative measure of the rate at which a particular molecule can cross a particular membrane; A = surface area C 1 - C 2 = the difference in concentration between two … WebFick's law describes the movement of particles over time.
