    Dr. Burrow
    I have another question that i couldn't solve

    The following reaction was monitored as a function of time:
    AB --> A + B
    A plot of 1/[AB] versus time yields a straight line with slope 5.4 x 10^-2 M.s

    If the initial [AB] is 0.290M, and the rxn mixture initially contains no products, what are the concentration of A and B after 80s.

    (this problem is about integrated rate law and half-life)
