Ammonia gas (A) and nitrogen gas (B) are diffusing in counterdiffusion through a straight glass tube 0.61m long at 298K and 101.32 kPa. The partial pressure of MH3is constant at 20.0kPa in one chamber and 6.666kPa in the other. If the diffusivity at 298K and 101.32kPa is 2.3*10^(-5)m^2/s

a)What is the flux of ammonia
b) Calculate the diffusion of ammonia if the diameter of the tube is 24.4mm.

Ammonia gas (A) is diffusing at steady-state through N2 (B) by equimolar counter-diffusion in a circular conduit 1.22 m long at 25 degrees celsius and a total pressure of 101.32 kPa absolute. The partial pressure of ammonia at the left end is 25.33 kPa and 5.066 kPa at the other end. The conduit has a diameter of 0.0305 m at the left end and tapering uniformly to 0.0610 m at the right end. The diffusivity is 0.023 x 10–4 m2...

Ammonia gas is diffusing at constant rate through a layer of stagnant air 1 mm thick. Conditions are fixed so that the gas contains 50% by volume of ammonia at one boundary of the stagnant layer. The ammonia at the other boundary is quickly absorbed and the concentration is zero. The temperature is 295 K and the pressure is 1 atm. If the diffusivity of ammonia in air is 0.18 cm2/s calculate the rate of diffusion of ammonia through the...

A gas of CH 4 and He is contained in a tube at 101.32 kPa pressure and 298 K. At one point the partial pressure of methane is p A1 = 60.79 kPa, and at the point 0.02 m distance away, p A2 = 20.26 kPa. If the total pressure is constant throughout the tube, calculate the flux of CH 4 (methane) at steady state for equimolar counterdiffusion

Ammonia gas is diffusing through N2 under steady-state conditions with N2 nondiffusing since its insoluble in one boundary. The total pressure is 1.013 x 104 Pa and the temperature is 298 k. The partial pressure of NH3 at one point is 1.333 Pa and at the other point 20 mm away it is 6.666 x 103 Pa. The DAB for the mixture at 1.013 x 105 Pa and 298 K is2.30 x 10-5 m2/s. a) Calculate the flux of NH3...

CHEMICAL ENGINEERING Two bulbs are connected by a straight tube, 0.001 m in diameter and 0.15 m in length. Initially the bulb at end 1 contains N2 and the bulb at end 2 contains H2. The pressure and temperature are maintained constant at 25°C and 1 atm. At a certain time after allowing diffusion to occur between the two bulbs, the nitrogen content of the gas at end 1 of the tube is 80 mol% and at end 2 is...

Water flows at 20 cm3/sec through a long straight tube that has an inner diameter of 1 cm. As the water flows, a toxin leaches from the tube into the water. At the inner surface of the tube, the toxin attains its saturation concentration, Csat = 2 mM. Fortunately, upon entering the water the toxin also irreversibly degrades into a non-toxic compound; this degradation follows first-order kinetics. Toxin Diffusivity D = 10-5 cm2/sec Toxin mass transfer coefficient k = 1.38...
