Rate Limiting Step

Postby BrianaBarr2A » Sat Mar 18, 2017 5:36 pm

In reaction mechanisms, how do we determine which step is the slow step if it is not given to us?

It is usually given to us. Otherwise, you can tell by the step that has the larger activation energy. This can be determined by the step that has more bonds that need to be broken/added.

Why is it that a larger activation energy indicates that it is the rate limiting step?? Is it because the step is slower?
