The solute HCl (A) is diffusing through a think film of water (B) 2.0 mm thick at 283 K. The concentration of HCl at point 1 at one boundary
of the film is 12.0 wt% HCl (ρ = 1060.7 kg/m³), and at the other boundary at point 2 it is 6.0wt% HCl (ρ = 1030.3 kg/m³). The diffusivity of HCl in water at 283 K is 2.5 × 10–9 m²/s. Calculate the flux of HCl if water is impermeable at the other boundary.
