Derive fick's second law
WebModel Derivation Fick’s second law given by Eq. 6 D ads o2 ox2 cxðÞ¼;t o ot cxðÞ ð;t 6Þ is solved assuming the mass transfer in the adsorptive boundary layer is described by the effective diffusivity D ads. Because the layer is dominated by adsorptive forces, the classical correlations for bulk liquid phase diffusion coefficients are ... WebFick's Second Law is a mathematical equation that describes the diffusion of particles or molecules in a medium over time. It states that the rate of change of concentration of particles is proportional to the second derivative of the concentration with respect to distance. View the full answer. Step 2/2.
