Fick's laws of diffusion

WebDec 16, 2024 · Fick’s law of diffusion is the law that explains the diffusion process in the derived form of equations. Diffusion is the spontaneous movement of atoms and moleculesfrom their higher concentration to lower concentration in space. It is so named because it was described by Adolf Fick in 1855.

WebFick’s laws are strictly empirical. Diffusion is driven by gradients of free energy rather than of chemical concentration: JA = −CAMA ∂µA ∂x so that DA = CAMA ∂µA ∂CA where the proportionality constant MA is known as the mobility of A.
