(a) Plot of dimensionless concentrations 𝑢 and 𝑣 versus dimensionless distance 𝑋 when the dimensionless parameter 𝛾_𝑠=5, 𝜐=1, and 𝑎=0.001 using (12) and (13). (b) Plot of concentrations [𝑆]_em and [𝑃]_em versus the thickness of the membrane 𝑑 for the experimental values of the parameters𝐷=0.045m²/s,𝜐=1, and 𝑎=15 using (6), (12), and (13).
