The liquid-phase reaction:
A + B → C,
follows an elementary rate law and is carried out isothermally in a flow system. The concentrations of the A and B feed streams are 2 M before mixing. The volumetric flow rate of each stream is 5 dm3/min, and the entering temperature is 300 K. The streams are mixed immediately before entering. Two reactors are available. One is a gray, 200.0-dm³ CSTR that can be heated to 77C or cooled to 0C, and the other is a white, 800.0-dm³ PFR operated at 300 K that cannot be heated or cooled but can be painted red or black. Note that k 0.07 dm³ /mol-min at 300 K and E 20 kcal/mol.
Which reactor and what conditions do you recommend? Explain the reason for your choice (e. g., color, cost, space available, weather conditions). Back up your reasoning with the appropriate calculations.
