Homework Help: CHEM- KINETICS

Posted by lucylu on Saturday, September 25, 2010 at 10:04pm.

Dinitrogen tetraoxide, N2O4, decomposes to nitrogen dioxide, NO2, in a first-order process.
If k = 2.5 x 103 s-1 at -5° Cand k = 3.5 x 104 s-1 at 25° C, what is the activation energy for the decomposition?
0.73 kJ/mol
58 kJ/mol
140 kJ/mol
580 kJ/mol

I am having massive problems with chemical kinetics so any help is good.

Can't you use the Arrhenius equation?
