The liquid-phase reaction

follows an elementary rate law and is carried out isothermally in a flow system. The concentrations of the A and B stream 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 immediatly before entering. Two reactors are available. One is a gray 200 dm³ CSTR that can be heated to 77C or cooled to 0C, and the other is a white 800 dm³ PFR operated at 300 K that cannot be heated or cooled but can be painted red or black. Note k=0.07 dm³/mol*min at 300 K and E=20 kcal/mol.

(e) What batch reactor volume would be necessary to process the same amount of species A per day as the flow reactors while achieving 90% conversion? Estimate the costo of the batch reactor.

(f) Write a couple of sentences describing what you learned from the problem and what you believe to be the point of the problem.
