Slow Step

Definition

In multi-step reactions, the slow step is the slowest phase that determines overall speed or rate because no other step can occur until this one finishes.

Rate-Determining Step:

This term refers to the slowest step in any sequence of reactions which determines its overall kinetics. It's like our relay race example - no matter how fast other runners are, if one person lags behind, they set pace for everyone else.

Intermediate Product/Species: These are substances formed during middle steps that get consumed before reaching final product. They're like pit stops in a long car race - they're part of the journey, but you don't see them at the finish line.

Transition State:

This is a high-energy state that reactants must pass through to become products. It's like climbing over a hill during your relay race - it's tough and requires energy, but once you're over it, you can coast down to the finish.
