Problem 3. (15 Points) Air is passed above an Arnold cell containing liquid toluene. The temperature is 298 K and the total system pressure of the gas headspace is a constant 1.01 x 10^4 Pa. The cell has a cross-sectional area of 0.8 cm2. a height of 13 cm. and a liquid depth of 3 cm. Using diffusivity data given in Appendix J of W3R. plot the molar flux (mol m^2 s^-1) and the liquid toluene level (cm) vs. time (hr^1). How long does it take for the toluene to be depleted? At 298 K. the vapor pressure and the specific gravity of toluene are 28.4 mm Hg and 0.866. respectively.
