STEADY STATE DIFFUSION (FICK’S FIRST LAW) On the basis of the above considerations, Fick’s First Law may be formulated as: \(\mathrm{J}=-\mathrm{D}\left(\dfrac{\mathrm{dc}}{\mathrm{dx}}\right)\) In words: The diffusive flux is proportional to the existing concentration gradient. The negative sign in this relationship …
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.
