Find the steady state molar flow rate of HCl, in mol/s, through the plastic wall of a spherical container at 25°C with an HCl solution inside and outside the container. The container has an outer diameter of 60 mm and a wall thickness of 20 mm. Assume the HCl concentration in the wall at r = 10 mm is maintained at 1.0 X 10-5 M and the HCl concentration in the wall at r = 30 mm is maintained at 1.0 X 10-6 M. The ionic diffusion coefficients in the membrane at 25°C are 9.31 X 10-3 mm2/s for H+ and 2.03 X 10-3 mm2/s for Cl−. Assume there is no current in this problem.
