The molecularity of a reaction can be:

RankGuru · Accepted Answer

**Molecularity** is the total number of reactant species taking part in an elementary chemical reaction that must collide simultaneously to bring about the reaction.
- It is a theoretical property of an **elementary step**.
- It must be a **positive integer** ($1, 2$ or $3$). It cannot be zero, fractional, or negative.
- Molecularity $> 3$ is extremely rare because the probability of more than three molecules colliding simultaneously with proper orientation is negligible.
