Question

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 feed streams are 2Mbefore 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-dm³CSTR that can be heated to 77^oC or cooled to0^oC, and the other is a white, 800.0-dm³PFR 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 andE=20 kcal/mol.

How long would it take to achieve 90% conversion in a 200-dm3batch reactor withC_AO=C_BO=1mafter mixing at a temperature of 77^oC?
