Because the layer is dominated by adsorptive forces, the classical correlations for bulk liquid phase diffusion coefficients are ... WebFick s second law defines the behavior of a diffusing chemical in space over time. Fick s second law is derived from Fick s first law and the equation of continuity for a solute. For simplicity, we derive Fick s second law in 1-D coordinates. This can readily be extended to multiple dimensions or to spherical coordinates [22]. [Pg.18]
