Derive fick's second law
WebDepartment of Chemistry UCI Department of Chemistry WebFick's second law is a differential equation with a solution the describes the concentration of a contaminant as a function of position and time, when the contaminant is only subjected to diffusion. Recall that Fick's 1st law, which describes diffusive flux F in a …
