A mixture of 65 mol% methane, 30 mol% hydrogen, and 5 mol% nitrogen is burned to heat a boiler used to produce hot steam. Unfortunately, the burner has corroded, leading to poor performance and the production of carbon monoxide. The ratio of CO2 to CO in the exhaust gas is 10:1. If 30% excess air is supplied, determine the concentration of the exhaust gas. Note, all of the methane and hydrogen is consumed
