(a) A gas phase reaction, ? → ? is carried out in a packed bed reactor (ID = 0.8 m) containing Al2O3 catalyst. The catalysts were of spherical shape with a diameter of 6 mm. The reactant A was diluted with inert (70% inert) and fed to the reactor at 10 atm and 200 °C. The volumetric flow rate was varied from 5 - 15 m3 /s. It was assumed that the surface reaction and the external mass transfer influenced the overall conversion in the reactor. Compare the amount of the catalyst required to achieve 50% conversion under different flow rates.

(b) Estimate the weight of the catalyst to achieve 50% conversion when the reaction was carried out at 400 °C for the feed flow rate of 5 m3 /s.
