Two bulbs are connected by a straight tube, 0.001 m in diameter and 0.15 m in length. Initially the bulb at end 1 contains N2 and the bulb at end 2 contains H2. The pressure and temperature are maintained constant at 25°C and 1 atm. Since the gas system is closed and at constant pressure and temperature, mass transfer in the connecting tube is equimolar counter diffusion. At steady state, the nitrogen content of the gas at end 1 of the tube is 80 mol% and at end 2 is 25 mol%. If the binary diffusion coefficient is 0.784 cm2/s, determine the rate of transfer of N2 and H2 in mol/s.
