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/MÂ·s) t(Â°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?
