takes place inside a catalyst monolith at 400 K and 101.3 kPa.

(a) Calculate the conversion in a monolith that is 0.3 m high, 0.3 m wide, and 1.0 m in length. The spacing between the 0.1-cm-thick plates is 0.5 cm. The molar feed rate is pure A at 30.5 mol/s.
(b) How would your answer change if the reaction
