Multi Step Reaction

Postby Alyssa McLeod 3E » Sun Feb 19, 2017 7:20 pm

In a multistep reaction, how do you determine which step is the slow, or limiting, step? That is, how do you know which reactants to ignore while setting up a rate equation?

The step that affects the rate law is considered the slow step.

I actually had a follow up question:
When looking at elementary steps to a reaction, how do we know which reverse reactions do not affect the overall rate of consumption/formation (15.8, page 634 in textbook). Thank you so much!
