In a catalytic reactor, spherical particles of radius = 0.3 cm are surrounded by a gaseous layer, 0.2 cm thick, through which the feed of a mixture A and B, containing 50% of A, diffuses and reacts on the surface. The reaction takes place according to the simplified equation A(g) B@ The rate of reaction at the surface with respect to component A(g) is described by: N,= KSA The system is at 300C and 1 atm, where K: -20 cm/s and Da-mix > DA-M=0.108 cm-/s. Reminder!!1 if needed. Taylor series. Considering only the first and second term of the Taylor series. we have: Ln(a + x) - Ln(a) + (12) It is asked: a) The diffusion rate (WA) in mol/s 02) What considerations differ the approach of the heterogeneous system in relation to the heterogeneous system? 03) Still in relation to problem 01: a) if it were limited by mass transport, how could we minimize this resistance? b) If limited by chemical kinetics, how could we minimize this resistance
