    Hi i need to find out what order of reaction it is when the graph of initial rate against concentration comes out with a negative gradient but where initial rate and concentration are proportional like this:

    |
    |--\
    |---\
    |----\
    |-----\
    |----- \
    |-------\
    |--------\
    |---------\
    |----------\
    |____________________________

    but without the (-)s


    i hope my amusing attempt at a diagram will trick you into a pity reply

    From the graph, your line is curved, The rate decreases as the concentration decreases and thus has a constant half life. The order of reaction will therefore be first.
    If the half life increases as the reaction goes on then the order is 2nd. But i think you have a first order.

    Rate decreases as concentration increases I thought..
