### 15.61 units

What is the unit of activation energy?

For 15.61, I used R = 8.314 J/(K*mol), and got my activation energy as Joules, but the solutions manual converted R into KJ, thus making unit of activation energy KJ.

Does it matter which one I use?

I supposed that it doesn't, but for simplicity sakes, I think it would be easier to convert your final answer into kJ to make it easier to read.
