WebFick’s Laws of Diffusion • Fick’s 1 st law – Accurately describes diffusion – No convenient measure of current density • Fick’s 2 nd law – Combines first law with continuity equation – Yields concentration over time as a function of second derivative of the concentration gradient through the diffusion constant Weba diffusion coefficient D. This version of Fick’s law is rarely used for interpreting simple transport studies. However, when assuming a time-independent linear concentration profile (Equation 3.2.4), Fick’s law becomes more straightforward to use, as we shall see later.
