An open tube, 1 mm in diameter and 6 in. long, has pure hydrogen blowing across one end and pure nitrogen blowing across the other. The temperature is 75°C.
(a) For equimolar counterdiffusion, what will be the rate of transfer of hydrogen into the nitrogen stream (molls)? Estimate the diffusivity from (3-36).
(b) For part (a), plot the mole fraction of hydrogen against distance from the end of the tube past which nitrogen is blown.
