1. Variable density for two reactors in series. The gas-phase irreversible and first-order reaction A 3B is carried out in a PFR, where the feed is equal molar of A and an inert gas. The conversion under these circumstances is 50 %. The exit from the PFR is fed to a CSTR of the same volume as the PFR under the same Pand T conditions. What is the conversion exiting the CSTR? Solve the problem numerically, as a function of Fa, F., and Fs. You can assume any arbitrary numbers to VR. Cao, Fao, and vo (let's say all = 1.0), since they will be the same for each reactor to obtain k and then solve for XA at the exit of the CSTR
