MN Chemicals desires to run the following gas phase reaction in an isothermal, isobaric (25 deg C, 101 kPa) reactor: A(g) + 2B(g) â†’ C(g, 1) + D(g)

It is determined that the rate law can be expressed as first order in both reactants. The saturation mole fraction of C in the gas phase is 0.25. Assume that A and B are fed at a stoichiometric ratio and the total volumetric flow rate is 1.5 L/min. The rate constant is 0.035 L/(mol's). Assume that all gaseous species behave as ideal gases.

Required:
a. Is this an elementary reaction/step?
b. Write out the stoichiometric table in terms of Xa and Fao for all species.
c. What is the vapor pressure of C? At what conversion of A does condensation of C begin?
d. Write (-rA) both before and after condensation as a function of conversion, the rate constant, and the initial concentration of A.
e. What volume of CSTR is required if you desire a conversion of 90% of A?
