Dear Carmen,
please see below the referee's comment to your revised version. I agree that error bars are necessary to demonstrate the experimental uncertainties, especially as AMT is a technical journal.
So, after you add appropriate error bars to the activation curves (especially Figures 3,4,5,6; exemplary error bars will do, they don't have to be shown for every data point), I will be happy to accept the manuscript for publication.

Best regards,
Johannes

referee comment:

I agree with the Authors with most of the replies, but disagree in one certain point. The lack of "error bars" in different figures was raised up, and I'm not happy with the answer "As the temperature difference between the curves is relative small errors bars were omitted in order to show the curves more clearly." Especially in the case when the differences are small the uncertainty should be presented in a way or another. Without any statistics presented the conclusions made on the observations can be too optimistic. I'm not asking it to be added to every single plot, but at least one with some discussion.
