Estimate the gas phase diffusion coefficient of ammonia (NH3) in Methanol at 1.0 atm and 373 K by making use of Brokaw equation in the calculations. The dipole moment (up) for NH3 is 1.46 debye, and the liquid molar volume at the normal boiling point (Vb) is 25.8 cmy/mole and Tb=239.7 K. The dipole moment (up) for Methanol is 1.70 debye, and the liquid molar volume at the normal boiling point (Vb) is 59.2 cm3/mole and Tb= 337.85 K. Assume A: NH3, B: Methanol 1. Calculate the mutual diffusion coefficient DAB at T=373 K and 1.0 atm (Hand calculation)
