Fick first law

WebFick's first law of diffusion describes the rate of diffusion of a solute through a medium. It states that the flux J of a solute across a unit area is proportional to the concentration gradient ∂C/∂x, where C is the concentration of the solute and x is the distance: J = -D (∂C/∂x) where D is the diffusion coefficient, which depends on ...

WebFick's first law. Fick's first law states that the diffusive flux goes from regions of high concentration to regions of low concentration, with a magnitude that is proportional to the concentration gradient and the proportionality constant is the diffusion coefficient.

WebFick’s first law describes the diffusion rate or flux as a function of the concentration gradient for a linear concentration profile, i.e. when the concentration gradient is constant, as shown in Figure 7.2.Fick’s second law generalises diffusion behaviour to cases in which the concentration profile is non-linear and the concentration gradient is not constant.
