    The second-order rate constant for the decomposition of nitrous oxide (N2O) into a nitrogen molecule and oxygen atom has been measured at different temperatures given below.

    k(1/M·s) t(°C)
    1.87 10-3 600
    0.0113 650
    0.0569 700
    0.244 750

    Determine graphically the activation energy for the reaction.

    I took 1/873 was my initial value for temp. then i subtracted this from my final temp. which was 1/1023. I divided this by the change in ln(k).

    my final answer was 2.86e-4 but it is incorrect. can you help me please?
