Problem: The stagnant liquid B in a container that is 10 cm high (L = 10 cm)is exposed to the non-reactant gas A at time t = 0. The concentration of A, dissolved physically in B, reaches cAo = 0.01mol/m3 at the interface instantly and remains constant. The diffusion coefficient of A in B is DAB = 2x10-9 m2/s. Determine the evolution of the concentration of A within the container. In the second part, repeat it but this time consider that A reacts with B according to the following reaction

A+B → C -rA = 2 x 10-7cA, mol/s.m3
