The liquid phase reaction A+B+C follows an elementary rate law and takes place in a 1 m CSTR, to which the volumetric flow rate is 0.5 m3/min and the entering concentration of A is 1 M. The reaction vessel is jacketed with cooling fluid to maintain isothermal operation at 300 K. For an equimolar feed of A and B, the conversion is 20%. When the reaction is carried out adiabatically, the temperature is 350 K, and the conversion is 40%. The heat capacities of A, B and C are 25, 35, and 60 kJ/mol/K, respectively. It is proposed to add a second reactor of the same size downstream in series with the first CSTR. The second CSTR is also jacketed, with UA = 4.0 kJ/min/K and the coolant fluid enters and exits at virtually the same temperature (350 K). a) What is the rate of heat removal from the first reactor necessary for isothermal operation?
b) What is the conversion exiting the second reactor?
