Finding Activation Energy From Arrhenius Plot

1. Homework Statement

For a lab, I need to find the activation energy of an experiment from plotting the Arrhenius plot. I have the half-life time of the reaction at various temperatures.

2. Homework Equations

-Temperature (K)
318
322
327
331
338

-ln k
-6.17
-5.89
-5.65
-5.33
-5.01

-1/T
3.145 x 10^-3
3.106 x 10^-3
3.058 x 10^-3
3.021 x 10^-3
2.956 x 10^-3

3. The Attempt at a Solution

So far I've plotted ln k vs 1/T.

Ok forget that. why would the concentration of H2O be ignored in a rate law reaction?

It would be ignored if the rate of the reaction was independent of H2O concentration.

Because it is a (l) and we only consider the concentrations of (aq) solutions.
