Question

The activation energy, Ea, for a zeroth-order 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!

Answer 1

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