Two glass bulbs are connected by a 0.2-m-long glass tube with a 0.001-m inner diameter. Initially, bulb 1 contains pure argon and bulb 2 contains pure xenon. Bulb 1 has a volume of 1 L. The absolute pressure and temperature are maintained at 1 atm and 110 oC, respectively. At a certain time, the contents of the two bulbs are analyzed and the argon mole fraction in bulb 1 is found to be 0.75, while the argon mole fraction in bulb 2 is found to be 0.20.

(a) Determine the volume of bulb 2.

(b) Assuming that only diffusion occurs in the connecting tube and that the mole fraction profile in the connecting tube is linear, for the given time determine the mass transfer fluxes of argon and xenon, the mass transfer rates, the component velocities  of argon and xenon in the tube at the bulb 1 end andat the bulb 2 end, and the molar average velocity of the mixture, . Thebinary diffusivity of Ar/Xe mixtures at this temperature and pressure is  = 0.115 cm²/s.
