Consider the following system of gas phase reactions; A --> X x = kCA/ k=0.004 (mol/dm)1/2 min-1 A --> BrB = kCA k=0.3 min- 2 A--> Yry=k3CA k=0.25 dm /mol-min B is the desired product, and X and Y are pollutants that are expensive to get rid of. The specific reaction rates are at 27C. The reaction system is to be operated at 27C and 4 atm. Pure A enters the system at a volumetric flowrate of 10 l/min. a) Sketch the instantaneous selectivities (SB/X, SB/Y and SB/XY) as a function of the concentration of CA. b) Consider a series of reactors. What should be 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 first reactor?
