A CSTR must be designed for a liquid phase reaction A products. The reaction is pseudo-first order
with respect to A, with A=4.01013s-1, and EA=90,000Jmol. The feed is an aqueous solution of
A(2.0M), with a density of 1.02kgL and a temperature of 320K. The heat capacity of the mixture is
3.9kJkg-1K-1, and the reaction is strongly exothermic, with an enthalpy of -50kJ per mol of A reacted.
a) The mathematical relationship between fA and T based upon the steady state material
balance is shown in graphical form on the next page. Show how this relationship is
developed, from first principles, based upon the information provided above.
b) Determine the maximum and minimum possible steady state conversion and operating
temperature that could be achieved in this system.
c) The failure of an upstream heat exchanger means that the inlet temperature of the feed is
reduced by 15C. What effect, if any, will this have upon system operation and steady state
operating conditions?
