    Using this data calculate the rate law for the reaction A + B -> C

    [A] (M) [B] (M) Initial rate (M/s)
    0.10 0.10 0.0092
    0.20 0.20 0.0184
    0.20 0.40 0.0368

    We use the general formula r=k[A]^x * [B]^y, and we'll use the second and third equations to solve (since the concentration of A does not change, it will make it easier)


    We'll get the x-term alone so we can ...
