Ficks first law equations
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.
