Methane is completely burned in a boiler with 20% excess air; 30% of the methane converts to CO and the remainder to CO2. If the barometric pressure is 740 mm Hg and the temperature of the stack gas is 150oC, what is the partial pressure (mm Hg) of the CO?

A mixture of 65 mol% methane, 30 mol% hydrogen, and 5 mol% nitrogen is burned to heat a boiler used to produce hot steam. 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.
