Could you please show your work? I know that the answer is supposed to be 20 but I do not know how to get there.

Rates of a reaction are sensitive to temperature. If a slow folding step (like a Pro isomerization) takes 9 minutes but you need to be able to measure it in 60 seconds, by how much and in what direction should T vary if the reaction rates increases by a factor of 3X for every 10 C in temperature?

Thank you
