Ammonia gas (A) is diffusing through a uniformtube 0.10 m long containing N2 gas (B) at1.0132×105 Pa pressure and 298 K. At point 1, PAI= 1.013 × 104 Pa and at point 2, PA2 = 0.507×104Pa. The diffusivity DAB=0.230 x 10-4 m²/s. (a) Calculate the flux J* (in kmol/s-m²) atsteady state. (b) Repeat for J*B (in kmol/s-m²).
