I don't know how to solve part(e)

i found the catalyst weight which is = 4.304 g cat

but I don't know how to find the CSTR volume

For the isothermal, isobaric, gas phase catalytic reactor carried out in a fluidized CSTR (Benzene to cyclohexene) and reaction follows elementary rate law and must be expressed in partial pressure. C6H6 + 2H2 CH10 The feed enters at 6 atm and 270 C (533K) and is a stoichiometric mixture. What catalyst weight is required to achieve 70% of conversion of benzene? mol The inlet molar flow rate of the limiting reactant is FAO = 2.28 min mol The reaction rate constant is, kg = 53x10-6 at 300K kg cat minam with activation energy, Ea = 80 and Gas constant, R, = 8.314 mot mol. K Hints: It is a gas phase reaction and you need to consider for the change in volumetric flow,( i.e. e) in concentration and partial pressure calculation. You need to construct the stoichiometric table and take care of temperature effect.
