Extracted text: QI / Ammonia gas (A) is diffusing through N2 (B) under steady -state conditions. The total pressure is (1.013*10 Pa) and 298 K. The partial pressure of NH; at one point is (1.333*10 Pa). At the other point 20 mm away, the partial pressure of N2 is (9.4634*10ʻ Pa). The DAB of the mixture at 0 °C and 3atm is (6.557 10* m/s): 1- Calculate the flux of ammonia if N; is nondiffusing. 2- Calculate the flux of ammonia if the both gases are diffusing equally 3- Caleulate the overall resistance to mass transfer relative to gas phase for equimolar counter diffusion (H=1.2). Neglect the effect of eddy diffusivity
