i need the solution

Student Number Question 1 (40 points) Consider the following system of gas-phase reactions m-ach *, -0.004(mol/dm3 min A B no CA k 0.3 min AY c. k, = 0.25 dm /mol min B is the desired product, and X and Y are foul pollutants that are expensive specific reaction rates are at 27C. The reaction system is to be operated at 27 = 0.162 mol/L). Pure A enters the system at a volumetrio flow rate of 10 dmm a) How does the selectivity of B (Sexy) vary with the concentration of A? b) Calculate/estimate the maximum value (Sexy). c) Consider a series of reactors. What should be the volume of the first res d) What are the effluent concentrations of A, B, X, and Y from the first re e) What is the conversion of A in the first reactor? f) If 95% conversion of A is desired, what reaction scheme and reactor si to maximize SB/xy?
