A thin film of water (species B) contains a solute HCl (species A). The thin film has a thickness of 2 mm and its temperature is 283 K. The concentration of HCl at the left side of the thin film is 16% w/v (the density of HCl at this point is 1081.5 kg/m). The concentration of HCl at the right side of the thin film is 6% w/v (the density of HCl at this point is 1030.3 kg/m?). The right side of the thin film is in contact with an impermeable material that prevents water from passing through it. However, HCl can pass through the material. The diffusion coefficient for HCl in water is 2.5x10-9 m-/sec. A. Assume that this is a dilute solution of HCl in water (XA is small enough). At steady- state, calculate the molar flux of HCl through the thin film using SI units. a B. Do not assume that this is a dilute solution (XA is not small enough). At steady-state, calculate the molar flux of HCl through the thin film using SI units, including convective mass transfer. (Hint: the problem statement tells you which species will have a non-zero convective mass transfer flux.] Be sure to: Correctly calculate HCl concentrations in units of molar at both points. Apply Fick's Law to calculate molar fluxes in both scenarios. Hints: XB = 1 - XA XA/(1-XA)=(1-XB)/XB The integral of (1-XB) / XB is log(XB) - XB
