    with catalytic converter NO (harmful) turns into NO2 (harmless).

    and the first enthalpy question (second page) was 2 x the enthalpy they gave u i think. since the reaction had 2NO2 and it gave u the enthalpy change of NO2.

    Oh right well in my text book it says catalytic converters convert nitrogen oxides into less harmfull gases like nitrogen? so i dunno probs could have put both, and yeah thanks for the enthalpy 1, i did x by 2 although i saw people saying you had to put a minus on the answer which i was unsure about.

    ah ****.. i think it is N2 and not NO2

    i had never read anything about nitrogen and catalytic converters so i just assumed it would be like carbon.. ah well
