A catalytic converter in an automobile uses a palladium or platinum catalyst (a substance that increases the rate of a reaction without being consumed by the reaction) to convert carbon monoxide gas to carbon dioxide according to the 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 745 torr and a temperature
