Into a combustion reactor, hexane at 23 mol/s and 75% excess dry air are fed. The fractional conversion of hexane is 30%. Assume that air is 21 mol% oxygen and 79 mol% nitrogen. HINT: Consider all the reactants that exit the reactor. a.  Draw a complete flowchart of the process. Clearly state any assumptions. b. Perform a degree-of-freedom analysis. Clearly state which type of DOF analysis you are doing. c. What is the mole fraction of carbon dioxide in the flue gas on a dry basis?
