a) Estimate the volume of a plug-flow reactor required to achieve 40% conversion of A for an entering
volumetric flow rate of 1.18 ft³/sec.
b) Estimate the volume of a CSTR required to take the effluent from the plug-flow reactor (PFR) above
and achieve 60% total conversion (based on species A fed to the PFR).
