Problem 2: The elementary irreversible gas-phase reaction 2AB+ 2C is carried out adiabatically in an isobaric PBR. Pure A enters the reactor at a volumetric flow rate of vo = 20 dm?/s, a pressure P = 10 atm and a temperature of TO = 450 K. Assume that all gases behave ideally. a. Derive an expression for dXA/W along the PBR in terms of XA, TO, T, VO, P, K, and any numerical constant b. Write an expression for T in this PBR in terms of XA and constants given in the problem. c. What will be the temperature at 85% conversion in this reactor? How does your answer change if you use an adiabatic CSTR instead of a PFR? Explain any similarities/differences between your answers.
