A reaction 2A--->B is second order with respect to A. Batch experiments have shown that, for an initial solution containing Ca=3mg/L, the concentration of A in a system can be reduced by 99% is 25 min.
a) What is the rate constant k2?
b) What would be the volume of a PFR to treat 100 L/min of this solution while meeting an effluent standard of 0.1 mg/L?
c) What would be the volume of a CFSTR to meet the same effluent standard of 0.1 mg/L?
