Molecular diffusion of HCl across an air film.HCl gas diffuses through a film of air 0.1 in. thick at 20oC. The partial pressure of HCl on one side of the film is 0.08 atm and zero on the other. Estimate the rate of diffusion in mol HCl/s-cm2, if the total pressure is (a) 10 atm, (b) 1 atm, (c) 0.1 atm. The diffusivity of HCl in air at 20oC and 1 atm is 0.145 cm2/s.
