A first order, liquid phase endothermic reaction A -> B + C, is conducted in a CSTR of 25 m3 volume operating at steady state. The feed concentration of A is 1.2 mol/L and enters the reactor at 8.7 L/s at 300 K. However, the reactor is heated in order to increase the rate and to achieve a conversion of 80%. a) Determine the temperature and heat transfer (kJ/s) requirement of the reactor needed to achieve this conversion. b) It is suggested to add a heat exchanger and a second reactor in series with the first CSTR. The coolant fluid enters and exits the reactor at a constant temperature which is less by 100 K from the exit temperature of the first reactor. Both reactors operate at the similar temperature. Calculate the conversion exiting the second reactor. Given that UA=2.3 kJ/s*K for which U is the overall heat transfer coefficient and A is the heat transfer area.
