question 4.31 in the Intro to Organic Chem book

Postby Miya Eberlein 1J » Tue Mar 01, 2016 3:42 pm

Hi, for #31 we're supposed give the overall rate law for the reaction. Why is the overall rate law for this reaction just the first step of the reaction? is there some significance to that?

Also, why is the rate constant larger for the second step, if it requires less activation energy? I'm having trouble connecting the two together.

thank you!

If the first step is the rate-determining step and it the rate law you write from it does not have intermediates, then you are done.

As for the second question, the pre-exponential factor A is not necessarily the same.
