1. You must design a continuous flow reactor scheme to produce the valuable secret product B, which is produced in the following liquid phase reaction: \text{A} \longrightarrow 2 \text{B} E/R = 250 K k? = 0.3 h?¹ at 295 K ?H°_{RX} (T_R) = - 100 kJ/mol A reacted T_R = 300 K -r_{1A} = k_1C_A C_{PA} = 6.4 kJ/(mol·K) C_{PB} = 3.2 kJ/(mol·K) The reagent A is purchased at a concentration of 1 M, and it is fed into the reactor at this concentration. In the warehouse is a 1000 L CSTR that is outfitted with a heating/cooling jacket. a. What is the volumetric flow rate of the feed stream to the CSTR, if it is necessary to achieve a concentration of B equal to 1.4 M in the product stream? Assume isothermal operation at 295 K. (5 points) b. How much heat must be added or removed to maintain isothermal operation of the CSTR? If you were not able to calculate a volumetric feed rate in (a), then you may use a value of 50 L/h. This may or may not be the correct answer to (a). (5 points) c. Unfortunately, the heating/cooling jacket has a leak in it, thus forcing adiabatic operation of the CSTR. How would you calculate the resulting concentration of B in the exit stream, if the entering feed stream temperature is 295K? Write all equations necessary to solve and carry calculations out as far as you can. (7 points) Because this problem requires guess-and-check or use of a solver, I will give full credit for the proper set-up and explanation of the solution strategy.
