Problem 1. (31 points) Carbon Dioxide is diffusing through a three-layer barrier material. The partial pressure on one side is P1 = 2.5 atm. The partial pressure on the other side is P2 = 0.3 atm. The thicknesses, CO2 diffusivities, and CO2 solubilities of the three layers are as follows: Layer Solubility m'solute (STP) Thickness (mm) 1.0 3.4 2.5 Diffusivity (cm/s) 6.7 x 106 2.4 x 10 1.5 x 10 msolldatm 0.90 0.045 0.75 11 a) How are the fluxes through the three layers related? (5 points) b) Sketch the concentration profiles of CO2 in the barrier layers: (6 points) P1 TTT P2 c) Determine the flux of Co, through the system in kgmol/ms. (20 points)
