### 15.89

I understand Step #2 is the slow step, but how do we know if Step #1 is faster than Step #3 (or vice versa)?

There would have to be more information give to you. You cannot make an assumption or an estimate based solely off the information they give you in the problem. Therefore, when you draw the graph, the Ea for either Step 1 or Step 3 can be higher, but there just isn't enough to make a judgement about which is more correct or more accurate.

I don't believe that we will ever have to determine which is the fastest, we most likely will be given information for that type of problem. If they give you multiple reactions, then we most likely will only have to determine the rate laws and compare it to the one given to us.
