Ammonia gas (A) and nitrogen (B) are diffusing in counterdiffusion 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 large mixed chambers at 101.32 kPa. The partial pressure of ammonia is constant at 20.0 kPa in one chamber and 6.666 kPa in the other. The diffusivity at 298 K and 101.32 kPa is 2.30 x 10-5 m²/s. Calculate: a) the diffusion of Ammonia gas in kg mol/s. b) the diffusion of nitrogen. c) the partial pressure at point 0.305m in the tube and plot PÃ, Pв and P versus distance, z.

Question
Transcribed Image Text:Ammonia gas (A) and nitrogen (B) are diffusing in counterdiffusion 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 large mixed chambers at 101.32 kPa. The partial pressure of ammonia is constant
at 20.0 kPa in one chamber and 6.666 kPa in the other. The diffusivity at 298 K and 101.32 kPa is
2.30 x 10-5 m²/s. Calculate:
a) the diffusion of Ammonia gas in kg mol/s.
b) the diffusion of nitrogen.
c) the partial pressure at point 0.305m in the tube and plot PÃ, PÅ and P versus distance, z.
