QUESTION 3 The gas phase reaction, 2A +B+C 1804 is carried out in a PFR at a temperature range of 100 - 500 C. The decomposition of B occurs at above 500C. The reaction follows elementary rate law in the above-mentioned temperature range with the specific rate constant k 0.025e(3.8-) (mmol''s'). The enthaupy of the reaction at 298 K was calculated as AHRx(298 K)=-110 kJ mot''. The reactant A is diluted with inert (1) at a ratio of 1/1 and is fed to the reactor at T = 473 K and P = 10 atm The volumetric flow rate of the feed, vo= 0.1 m's!. Cpa= 160 moll K; CpB = 320 mol'' K'; Cpu = 25 J mol' K'. a) Verify if the reactor can be run adiabatically to produce 3.5 mol/s of B. (7Marks) [C5, C04, PO31 b) A chemical engineer suggested to reduce the temperature of the feed is to 373K. In this case the required conversion is also decreased for the production of 3.5 mol/s of B due to the increase in Fao. Plot the conversion and temperature as a function of reactor volume.
