Engineers Milo and Christine operate a reactor producing a polymer(PM) by the following balanced, reversible chemical reaction: 2A+1B1PM+4W. A and B are secret building block components and W is water (H2O). The feed to the reactor is 408mol/hr with 0.572 mole fraction of A and the remaining B. The reaction does not go to completion in the reactor, but the exiting components are in chemical reaction equilibrium. The stream exiting the reactor contains a mole fraction of polymer of 0.147. In the last level, the component molar flow rates exiting the reactor were found as: 63.5mol/hrA,89.6 mol/hrB,85.0mol/hrPM, and 3.40E+2mol/hrW. Calculate the equilibrium constant at the exit of the reactor. Keq=
