B is the desired product, and X and Y are foul pollutants that are expensive to get rid of. The specific reaction rates are at 27°C. The reaction system is to be operated at 27C and 4 atm. Pure A enters the system at a volumetric flow rate of 10 dm^3/min.

a. Sketch the instantaneous selectivities (SB/X , SB/Y, and SBXY= rB/(rx+y)) as a function of the concentration of CA
b. Consider a series of reactors. What should be the volume of the first reactor?
c. What are the effluent concentrations of A, B, X, and Y from the first reactor?
d. What is the conversion of A in the first reactor?
e. If 99% conversion of A is desired, what reaction scheme and reactor sizes should you use to maximize SB/XY?
f. Suppose that E1= 20,000 cal/mol, E2=10,000 cal/mol, and E3= 30,000 cal/mol. What temperature would you recommend for a single CSTR with and an entering concentration of A of 0.1 mol/dm^3.
g. If you could vary the pressure between 1 and 100 atm, what pressure would you choose?
