A gas-solid catalytic reaction is carried out in an adiabatic fixed-bed cylindrical reactor. A gas mixture, which is assumed to behave as an ideal gas, enters the reactor with a flow rate (Q_f) of 25275 kmol h-1. The reactor operates at an absolute pressure of 22.3 bar and 535 K, and the catalyst pellets used are all spherical. Considering this information, and the data provided in Table Q3.2., calculate:
