# Problem: A catalytic converter in an automobile uses a palladium or platinum catalyst to convert carbon monoxide gas to carbon dioxide according to the following reaction: 2 CO(g) + O2(g) → 2 CO2(g)A chemist researching the effectiveness of a new catalyst combines a 2.0:1.0 mole ratio mixture of carbon monoxide and oxygen gas (respectively) over the catalyst in a 2.45-L flask at a total pressure of 750 torr and a temperature of 552˚C. When the reaction is complete, the pressure in the flask has dropped to 556 torr. What percentage of the carbon monoxide was converted to carbon dioxide?
