Hydrogen is diffusing through a uniform tube which contains nitrogen at pressure of 1 atm and temperature of 25C. If the concentration of hydrogen at one end is 20 mole% and at the other end, 200 mm apart, is 10 mole%, assuming steady state and equi-molar counter diffusion, calculate: a) The flux of hydrogen b) The rate of diffusion of hydrogen if the internal diameter of the tube is 50 mm c) The flux of nitrogen d) Compare your answers from part (a) and part (c) and comment Given: Diffusivity of hydrogen in nitrogen and that of nitrogen in hydrogen as 7.84 x 10 m/sec Gas constant (R) = 8.314 J/mol.K
