- Consecutive reactions involve sequential steps where an intermediate is formed and then consumed.
- For A→I→P, rate laws are d[A]/dt=-k₁[A], d[I]/dt=k₁[A]-k₂[I], d[P]/dt=k₂[I].
- The intermediate's concentration typically peaks before decaying in consecutive reactions.
- Autocatalysis occurs when a reaction product itself catalyzes the reaction.
