Question

Ammonia gas (component-A) and nitrogen gas (component-B) are diffusing in counter-diffusion through a straight glass tube 0.610-m long with an inside diameter of 24.4-mm at 298 K and 101.32 kPa. Both ends of the tube are connected to a large mixed chambers at 101.32 kPa. The partial pressure of NH3 in one chamber is constant at 20.0 kPa and 6.666 kPa in the other chamber. The diffusivity at 298 K and 101.32 kPa is 2.30 x 10-5 m2/s
(a) Calculate the diffusion of NH3 in kg-mole/s
(b) Calculate the diffusion of N2 in kg-mole/s
(c) Calculate the partial pressures at a point 0.305-m in the tube
