i would like polymath solution thanks

AXABAYrX=k1CA1/2rB=k2CArY=k3CA2k1=0.004(mol/dm3)1/2mink2=0.3min1k3=0.25dm3/molmin B is the desired produet, and X and Y are foul pollutants that are cxpensive to get rid of. The specific reaction ratcs are at 27C. The reaction system is to bc operated at 27C and 4 atm. Pure A cnters the system at a volumetric flow rate of 10dm3/min. (a) Sketch the instantaneous sclectivities (SBXSB. and SBXY=rB/(rX+rY)) as a function of the concentration of CA. (b) Consider a series of reactors. What should be the volunc of the first reactor? (c) What arc the effluent concentrations of A.B.X, and Y from the first reactor. 364 Multiple Reactions (d) What is the conversion of A in the first reactor? (e) If 99% conversion of A is desired. what reaction scheme and sizes should you use to maxinize SB/XY ? (f) Suppose that E1=20.000cal/mol.E2=10.000calool, and E3=31 cal/mol. What temperature would you recommend for a single CSTR a space time of 10 min and an entering concentration of A of 0.1mol/ (g) If you could vary the pressure between I and 100 atm. what pre would you choose
