3. Two isothermal CSTRs are used for a 1st-order liquid- phase reaction. Both operate at the same temperature and the same inlet volumetric feed rate. Estimate how the volumes of reactor 1 and 2 compare. (0.5 P) A. V₁ = 2V2 B. V₁ = 4.5V2 C. V₁ = 9V2 D. V₁ = 36V2 E. None of the above CRO 90% conversion CRO 20% conversion V2
