Pure chlorine gas at 1 atm is contained in a 195 cm3 bulb from which a 1-mm ID capillary 12 cm long leads to the atmosphere. The concentration of chlorine gas in the bulb can be assumed to be uniform at any time. The concentration of chlorine at the top of the capillary is essentially zero. How long will it take for the mole fraction of chlorine in the bulb to fall to 0.10 at 20 C
