### "Bottle Neck"

Lavelle mentioned mentioned this term when talking about intermediates, can someone please explain what he meant?

What the bottleneck means is that the first step prior to the slow step is assumed to be in equilibrium. If the early step is fast and the later step is slow, then there is a bottleneck and a buildup of intermediate results in the 1st step at equilibrium. Because of the bottleneck, we can do the pre-equilibrium approach.

Bottleneck is when the step prior to the first step before the slow one is at equilibrium. If the first one is fast then the second one is slow there will be a buildup of products which means the reaction will go back
