Pre-Equilibrium Approach

[Ryan Danis 1J]

For what type of question would I need to use the pre-equilibrium approach? I did not encounter any book problems where I had to use it.

[caseygilles 1E]

We use the pre equilibrium approach when the reaction is a fast step followed by a slow step. For pre equilibrium we assume the reaction before the rate limiting step is at equilibrium so we use K. This approach works because there is a bottle neck and a buildup of intermediate which results in the first step at equilibrium

If you want practice with it, you have to use this approach in 7.23 (b) (7th edition) to find the rate law.
