Homework Help: First Order Reaction

  1. Feb 6, 2006 #1
    The first-order reaction, SO2Cl2 --> SO2 + Cl2, has a rate constant equal to 2.20 x 10-5 s-1 at 593 K. What percentage of the initial amount SO2Cl2 will remain after 2.00 hours?





    ln [a]t/[a]0 = -kt

    ln [a] = -(2.20 x 10-5 s-1)(7200 s)

    ratio of a = e^-0.1584 = 0.8535

    Is this correct? Thanks.
