The hot exhaust gas from an internal combustion engine is analyzed and found to have the following percent composition on a volumetric basis at the engine exhaust manifold. 10% CO2, 2% CO, 13% H2O, 3% O2 and 72% N2, this gas is fed to an exhaust gas reactor and mixed with a certain amount of air to eliminate the carbon monoxide. It has been determined that a mole fraction of 10% oxygen in the mixture at state 3 will ensure that no CO remains. What must the ratio of flows be entering the reactor?
