Can you emphasise on i want to know the recommendation on solving this problem on that post?

The gas-phase dimerization is described as follow: 2AB This chemical reaction follows an elementary rate law and takes place isothermally in a PBR charged with 1.0 kg of catalyst. The feed consisting of pure A enters the PBR at a pressure of 20 atm. The conversion exiting the PBR is 0.3 and the pressure at the exit of the PBR is 5 atm. a) Examine the conversion at the exit of the CSTR if the PBR is replaced by a "fluidized CSTR with 1 kg of catalyst. You may assume that there is no pressure drop in CSTR. b) Determine the conversion in the PBR if the mass flow rate were decreased by a factor of 4 and particle size were doubled. You may assume the flow is a turbulent flow
