can you help me wih B plaese

Question two (answer either A or B) A. Pure A is fed at a volumetric flow rate of 103 ft/h and a concentration of 5x10-Ibmol/ft to a CSTR that is connected in series to a PFR. If the volumes of the CSTR and PFR wer 1200 ft and 600 ft respectively as shown below, calculate the intermediate and final conversions (XAI and XA2) that can be achieved with existing system. Reaction kinetics is shown in the graph below. 800 700 600 500 1/-r. (ft.h/Ibmol) 400 300 200 100 (1/-ra) = 260.42x + 1354.2x - 510.42x2 + 95.833x + 200 0 0 0.2 0.8 0.4 0.6 Conversion, X B. The reaction AB, r = k CA is to be run in continuous reactors with Cao = 3 moles/liter, k= 2 min"', v. = 5 liters/min. i. At 50% conversion, what is the required volume if a CSTR to be used V: 3.75 Liter ii. Calculate space time (T) for the CSTR 0.75 min = 0,0125h v iii. At 50% conversion, what volume PFR is required? v= 1,8 75 liter iv. If the effluent from the CSTR is fed into a second equal-volume CSTR, what is the overall conversion? X= 0,5 X2 = 0,5, Xovegan - 1 If the effluent from the CSTR is fed into a second equal-volume PFR, what is the overall conversion
