### Speed of a reaction

How do we determine of a certain reaction is slow or fast in 7C?

The size of the rate law will generally tell you how fast the rate is relative to other rates.

Generally, if a reaction occurs in multiple steps, the slow reaction is the rate-determining step. So, if the rate law is given, look at the multistep reaction and find which reaction corresponds to the rate law, and this will be the slow reaction and the remaining reactions fast. I also think that no intermediates can be in the rate law, so if a reaction is said to be slow but it contains intermediates, you have to substitute in the reactants that formed the intermediate and rework the constants of equilibrium!

Hope this helps!
