1. The reaction for the decomposition of dinitrogen monoxide gas to form oxygen radicals is:
N2O(g) --> N2(g) + O(g). If the rate constant is 0.0368 s-1 and the frequency factor is 8.00x1011 s-1, what is the activation energy for the first-order reaction at 710 degreesC? Units: kJ/mol

What I did: ln(0.0368)=ln(8.00E11)-(ea/8.314)(1/983...
ln(0.0368)-ln(800E11)/983.15(8.314)=-Ea
Ea= .0037
But the Correct answer is: 250.98
