WebI have a problem understanding the derivation of Fick's first law. I have used the following link as a guide: http://web.mit.edu/biophysics/sbio/PDFs/L15_notes.pdf I liked that way of … WebFick's first law. Fick's first law relates the diffusive flux to the concentration under the assumption of steady state.It postulates that the flux goes from regions of high concentration to regions of low concentration, with a magnitude that is proportional to the concentration gradient (spatial derivative), or in simplistic terms the concept that a solute will move …

A Direct Derivation of Fick’s Law for Multicomponent Diffusion
WebNow we move on to the Fick's second law. So previously, the Fick's first law doesn't have a time term there. So, how about the situations where time is a parameter in the diffusion problem? So this is what described by Fick's second law. So essentially the derivation of the Fick's second law, the derivation of the second law is the combination ... WebIt isn't quite Fick's second law yet. We need to incorporate Fick's First law into it to get an equation that we can actually solve to get concentration profiles. So we substitute the expressions from Fick's First Law for all the fluxes and get: We can simplify this: Notice how we took D out of the derivative. Why can we do this?
