he elementary liquid-phase reaction:

A + B -----> C

is to be carried out non-isothermally in a flow system with reaction constant,k= 0.07 dm^3mol-1min-1at 300K. The concentrations of each feed stream of A and B is 2 mol dm-3. The volumetric flow rate of each feed stream is 5 dm^3min-1. The two steams are mixed immediately prior to entering the reactor system. This flow system is conducted at 300K with two reactors: a 200 dm^3 stainless steel CSTR and an 800 dm^3 steel PFR.

(a)Determine the conversion that would be operated if both the CSTR and PFR were operated in series with the CSTR preceding the PFR.

(b)Determine the conversion that would be obtained if both CSTR and PFR were operated in parallel with 5 mol min-1fed to each reactor.
