2. Diffusivity and Schmidt number for a chlorine-air mixture a) Estimate DAB (in cm²/s) for chlorine (A) - air (B) mixtures at 297 K and 1 atm using the Chapman-Enskog relation (Eqn 17.7-12). Treat air as a single substance with Lennard- Jones parameters b) Use the results of (a) to estimate Schmidt number for a chlorine-air mixture at 297 K and 1 atm with a mole fraction of chlorine of 0.25 and a mixture viscosity of 0.0164 cP. Assume this mixture is an ideal gas.
