The activation energy, Ea, for a zerothorder reaction, X>products, is most readily obtained from the slope of a plot of: (choose from below)
[X] vs time
ln k vs time
rate vs time
[X]^2 vs time
ln[X] vs time
1/[X] vs time
ln k vs 1/T, where T is temperature in
ln k vs T, where T is temperature in K
k vs 1/T, where T is temp in K
I thought it was the 3rd last answer but im not too sure.
Thanks!

DrBob222,
If plot ln k vs 1/T
then slope = Ea/RT
