The following liquid phase parallel reactions are carried out in a plug flow reactor: (1) A+S0.3D, where tA rewction =k1CA20C512 (2) A+S0.5U, where tha reactona =k2CAACS0.5 The desired compound is D,and the numerical value of k1 is 1.4 the numerical value of K2, and both rate constants are in the mol, L, min units system. If the inlet concentrations of A and S are, respectively, 5.52 and 1.74molL1. What is the instantaneous selectivity of D over U if the conversion of the limiting reactant is 0.69? Express your answer to one decimal place
