    QUESTION PAPER:
    http://pmt.physicsandmathstutor.com/...Rates%20QP.pdf

    MARK SCHEME: http://pmt.physicsandmathstutor.com/...Rates%20MS.pdf

    For the first question, how do i know which value of [NO] to choose
    I know that the rate has to correspond to the concentration of NO
    Or does it not matter which concentration of NO I choose, just as long as [NO] and rate correspond?
    if so, why is this?

    It tells you in the mark scheme: ''Note: rate and [NO] are any correct pair of readings from the graph,''
