2. Consider the following system of gas-phase reactions: AX, 1x =k,CA!, ki = 0.004 (mol/dm)12 min! A B.13 = kxCA, K2=0.3 min! AY, Ty=k_CA?.kz=0.25 dm? /mol min 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 27C. 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 min. (1) Calculate instantaneous selectivities Swx. Spy, and Sexy as a function of the concentration of CA (2) What type of reactor and maximum of CA* you will choose to maximize Ssxy? (3) If you choose CSTR, what is the volume of the CSTR? What is the conversion of A? What are the efluent concentrations of A, B, X, and Y? (4) Suppose E = 20000 cal/mol, Ex = 10000 cal/ mol, and Ex - 30000 cal/mol. What temperature would you recommend for CSTR with a space time of 10 min and an entering concentration of A of 0.1 mol/dm
