Ammonia (A) is diffusing at steady-state through N₂
(B) by equimolar counter diffusion in a conduit 1.22 m long at 25°C and a total pressure of 101.32 kPa abs. The partial pressure of ammonia at the left end is 25.33
kPa and at the other end 5.066 kPa. The cross-section of the conduit is circular with diameter of 0.0610 m on the left end and tapering uniformly to 0.0305 m at the right end. Calculate the molar flux of ammonia. The
diffusivity of ammonia in Nitrogen is 0.230 x 10^-4
m²/s
