Question

Ammonia gas is diffusing through N2 under steady state condition with N2 nondiffusing since it is insoluble in one boundary. The total pressure is 0.1013 MPa and the temperature is 298 K. The partial pressure of NH3 at one point is 13.33 kPa and at the other point 25mm away it is 6.666×10^3 Pa. The Dab for the mixture at 1.013 ×10^5 Pa and 298 K is 2.30×10^-5 m^2/a.

a) calculate the flux of NH3 in kgmol/s.m^2

b) Assuming that N2 also diffuses (I.e. both boundaries are permeable to both gases  and the flux is equimolar counter diffusion, under the same condition as in question (a), determine the flux of NH3 I  kgmol/s.m^2
