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 25o C and 1 atm. At a certain time after allowing diffusion (equimolar) to occur between the two bulbs, 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: (a) The rates and directions of mass transfer of hydrogen and nitrogen in mol/s. (b)The velocities for N2 and H2 at z= 5 cm relative to stationary coordinates, in cm/s. (c) The velocities for N2 and H2 at z= 10 cm relative to stationary coordinates, in cm/s.
