What are the different types of molecularity and what do they mean?

- Unimolecular reaction: only 1 reactant molecule participates, molecularity =1
- Bimolecular reaction: two reactant species come together to react, molecularity=2
- Termolecular reaction: the collision of 3 molecules & uncommon

A reaction can be unimolecular with only one reactant molecule, bimolecular where two reactant molecules collide, and termolecular where three molecules must collide at the right orientation and with enough energy to cause a reaction. It is much more difficult for three molecules to collide perfectly to cause a reaction so the reaction rate is much slower than a bi or unimolecular reaction.

The three types are unimolecular, bimolecular, and termolecular. It depends on how many reactants there are in the rate law.

Unimolecular--1 reactant molecule
Bimolecular--2 reactant molecules
Termolecular--3 reactant molecules
