    you need initial rate and the rate concentrations of all components and rearrange to get k to get on its own, and then cancel to get units

    Probably better for you to give a little more info as it really does depend on what you've been given :p:

    However commonly determining from the rate equation:

    rate = k[A][B]

    if you have rate and the concentrations of A and B then: k = rate/([A][B])

    It's a very long question, but from the formula you have given i understand how to work it out now
    thanks
