The slowest step of the multistep reaction is known as the rate-determining step.
- A reaction mechanism is the sequence of elementary steps by which a chemical reaction occurs.
- A reaction that occurs in two or more elementary steps is called a multistep or complex reaction.
- The slowest step in a reaction mechanism is known as the rate-determining step.
Two conditions must follow:
- The equations for the elementary steps in the mechanism must add up to the overall equation for the reaction.
- The mechanism must be consistent with the experimental rate law.
