molecularity
This term is a specialized technical descriptor used exclusively within the field of chemical kinetics. It describes the stoichiometry of a single elementary reaction step, distinguishing it from the overall reaction order, which is an experimentally determined value.
Because it refers to a specific property of a chemical process, it is treated as an uncountable noun. It does not refer to a collection of items but to a conceptual measurement or characteristic of a reaction mechanism.
Meanings
Examples
The molecularity of this elementary reaction is two.

A trimolecular molecularity is rare because it requires three molecules to collide simultaneously.
Check the molecularity of the reaction before you write the rate law.
The professor explained that molecularity only applies to elementary steps, not overall reactions.
