What is Ficks first law diffusion?
Diffusion occurs in response to a concentration gradient expressed as the change in concentration due to a change in position, . The local rule for movement or flux J is given by Fick's 1st law of diffusion: ... The flux J is driven by the negative gradient in the direction of increasing x.
2 law
Fick's 2nd law of diffusion describes the rate of accumulation (or depletion) of concentration within the volume as proportional to the local curvature of the concentration gradient.

There are two laws that are interrelated ie; Fick's first law is used to derive Fick's second law which is similar to the diffusion equation
