3. For the given reaction; A+BC Series connection of three adiabatic plug flow reactors, with intercooler in between, is used to produce C. The feed to che first reactor consists of 40%A and 60% B. Data are given below for the reaction. a) Calculate the molar flow rates of the reactants and product (FA1,FB1,FC1) at the exit of the first reactor. b) Set up the necessary equations (material and energy balances) for the design of second reactor to obtain an expression for exit temperature of second reactor (T2f) at constant Cp. Give your design procedure shortly to find out the volume of second reactor (no need to make the numerical calculation for the volume of reactor)
