The Non-Fick Analytics in Transient Diffusion Mass Transfer with the Second Order Homogeneous Chemical Reaction

Based on the Pick's first law, the transient diffusion mass transfer with the second order homogeneous chemical reaction was analyzed. The result shows; when the intensity of chemical reaction is posititive, the non-Fick analytic solution of second order reaction is obviously higher than that of the first order reaction; When the intensity of that is negative, the result is the opposite.
