    One of the reactions in the catalytic converter of a car exhaust is

    2NO(g) + 2CO(g) o 2CO2(g) + N2(g)

    400 cm3 of NO is mixed with 500 cm3 of CO. What is the total volume of gas when the reaction is complete?

    All gas volumes are measured at the same temperature and pressure.

    A 600 cm3

    B 700 cm3

    C 1300 cm3

    D The volume cannot be calculated without the molar volume of gas at the appropriate
    temperature and pressure.

    It won’t let me upload the image of my workings out but I think the answer is B
