In certain combustion reactors, the reaction rate is autocatalytic in that the higher conversion you have, the greater the reaction rate. You have postulated the following reaction mechanism: Upon your direction, your lab technician measured the reaction rate as a function of conversion and plotted the data below in Figure 1. The reactant feed rate of A is 1 kg/hr and CAO = 0.3 g/cm³. (₁6) 1 0.8 0.6 0.4 0.2 0.2 0.4 XA k1 A → 2X 0.6 0.8 1 a) What size CSTR is necessary to achieve 40% conversion of A? b) What size CSTR is necessary to achieve 90% conversion of A? c) What conversion could you achieve with a 40 liter CSTR? d) What conversion could you achieve with a 40 liter PFR?
