= Molecularity
{wiki=Molecularity}
Molecularity refers to the number of reactant molecules that participate in an elementary reaction step. It is an important concept in reaction kinetics, as it helps to characterize the mechanism of chemical reactions. There are three main types of molecularity based on the number of molecules involved: 1. **Unimolecular**: Involves a single molecule undergoing a reaction. For example, the decomposition of a compound into simpler products is a unimolecular reaction.
