Fick's law

Etymology: Adolf E. Fick, German physiologist, 1829-1901

1 (in chemistry and physics) an observed law stating that the rate at which one substance diffuses through another is directly proportional to the concentration gradient of the diffusing substance.

2 (in medicine) an observed law stating that the rate of diffusion across a membrane is directly proportional to the concentration gradient of the substance on the two sides of the membrane and inversely related to the thickness of the membrane.
