300moles/h of octane (C8H18) are fed into a reactor. A separate stream (n2 mol/h) is also fed to the reactor containing 20% excess air. The octane combusts in the reactor, but not completely. The overall percentage conversion of octane is 80% and the gas leaving the reactor contains 20mol/hCO. a. Draw and completely label the flow chart for this process (use only species flow rates in units of mol/h for the outlet) b. Write out the two reactions that occur. Make sure the stoichiometry is balanced. c. Carry out a DoF analysis using the extent of reaction approach. d. How much air is fed to the reactor (n2 mol/h) e. Write out (but DO NOT SOLVE) all the equations required to solve for the unknown flow rates
