An engineer was trying to minimize greenhouse gases from car exhaust and was studying the gases that come from the trail pipe of a car at 800K. He discovered that 2 moles of carbon dioxide can react to form carbon monoxide gas and oxygen gas. He collects 5.00 L of an equilibrium mixture of the exhaust and determines that he has 5.23 M CO2, 0.125 M CO, and 0.256 MO2. In an attempt to minimize the polluting carbon monoxide he adds to the mixture 0.250 moles of oxygen gas. What will the new concentration of carbon monoxide be?
