Pure gas A diffuses from point 1 at a partial pressure of 101.32 kPa to point 2 a distance 2.0 mm away. At point 2 it undergoes a chemical reaction at the flat catalyst surface and A → 2B. Component B diffuses back at steady state. The total pressure is P = 101.32 kPa. The temperature is 300 K and DAB 0.15 x 10 m²/s. Gas constant, R = 8.314 m³ Pa/mol.K. (1) For instantaneous rate (very fast) of reaction, derive the equation for NA. (2) Calculate yA2 and NA in the case (1). = (3) For a slow reaction where reaction rate is ks CAs, derive the equation for NA. The equation can be implicit for NA.
