1. Estimate the DAB for the CO-CO system, at 2 atm pressure and 341.6 K.

2. The diffusivity of the Methanol-Carbon Dioxide gas couple can be determined by the steady-state evaporation of methanol in a tube with carbon dioxide, the distance between the liquid methanol and the top of the tube is 30.5 cm. The Total system pressure is 618 mm Hg and the temperature is 2C, look up data for the vapor pressure of methanol. The cross-sectional area of the tube is 0.94 cm?. It was found that 0.117 cm? of methanol evaporate in 6 hours. With these data, estimate the DAB.
