 Problem 3. Steady-state diffusion through a bilayer A flat bilayer slab

Problem 3. Steady-state diffusion through a bilayer A flat bilayer slab is composed of layers of material A and B, each of thickness L. A component is diffusing through the bilayer in the steady state under conditions where its concentration is maintained at c=co= constant at one surface and at c=0 at the other. Its diffusivity is equal to the constants DA and DB in the two layers, respectively. No other components in the system diffuse significantly. Let c be the concentration at the A-B interface. 1. Find the concentration profile cA(x) and the flux JA inside the A layer, where 0
