Ammonia and nitrogen gases diffuse in opposite directions through a straight glass tube 0.5 m long with an interior diameter of 3 cm at 25 oC and atmospheric pressure. Both ends of the tube are connected to enormous mixed chambers at atmospheric pressure. The partial pressure of ammonia gas in one chamber is constant at 165 mmHg, whereas it is 52 mmHg in the other. At 25°C, the diffusivity is 3.1 X 10-5 m2/s. Calculate the ammonia gas diffusion rate in lb mol/h and the nitrogen gas diffusion rate in kg mol/s.
