Question 1 The gas-phase reaction: A+B+C+D takes place isothermally at 300 K in a packed-bed reactor in which the feed is equal molar in A and B with CAO = 0.1 mol/dm3. The reaction is second order in A and zero order in B. Currently, 50% conversion is achieved in a reactor with 100 kg of catalysts for a volumetric flow rate 100 dm3/min. The pressure-drop parameter, q, is a =0.0099 kg-1. If the activation energy is 10000 cal/mol, what is the specific reaction-rate constant at 400 K
