Homework Help: Determining intial rates of reaction

    problem states:

    C2H5Br + OH- --> C2H5OH + Br-

    if the reaction mixture is .16 M C2H5Br and .26 M OH-, then what is the intial rate of reaction at 85 degrees.

    they also give a table of different temperatures and the associated k values at each. i also determined the activation energy and frequency factor for the reaction (if it matters at all for this question).

    my main question is, is the fact that there are two different concentrations given make a difference in the answer? how do i use those numbers? shouldnt they be the same if the reaction is at equilibrium?

    What is rate equation?

    i think i solved it:

    rate = k[C2H5Br ][OH]
