Ammonia gas (A) diffuses through nitrogen gas (B) under steady state conditions with nitrogen non-diffusing. The partial pressure of A at location 1 is 1.5 x 10* Pa and that at location 2 is 5 x 10³ Pa. the location 1 and 2 are 15 cm apart. The total pressure is 1.103 x 10$ Pa and temperature is 298 K. calculate the flux of diffusion of ammonia. Also calculate flux of diffusion for equimolar counter diffusion assuming that nitrogen is also diffusing. Take diffusivity at prevailing conditions are 2.30 x 10$ m²/s.

Question
Ammonia gas (A) diffuses through nitrogen gas (B) under steady state
conditions with nitrogen non-diffusing. The partial pressure of A at location 1
is 1.5 x 10* Pa and that at location 2 is 5 x 10³ Pa. the location 1 and 2 are 15
cm apart. The total pressure is 1.103 x 10$ Pa and temperature is 298 K.
calculate the flux of diffusion of ammonia. Also calculate flux of diffusion for
equimolar counter diffusion assuming that nitrogen is also diffusing. Take
diffusivity at prevailing conditions are 2.30 x 105 m²/s.
