    When petrol is burned in the engine of a car, the combustion is not complete and some carbon monoxide, CO, is produced. Nitrogen monoxide. NO, is another exhaust gas. These gases can be removed by a catalytic converter in the exhaust system.
    NO(g) + CO(g) ---> CO2(g) + 1/2N2(g)

    b. Explain why petrol that contain lead should not be used in cars fitted with a catalytic converter.
