Molecularity of Reaction
The number of reacting species (atoms, ions or molecules) taking part in an elementary reaction which must collide simultaneously in order to bring about a chemical reaction is Molecularity.
Description:
$\mathrm{NH}_4 \mathrm{NO}_2 \rightarrow \mathrm{~N}_2+2 \mathrm{H}_2 \mathrm{O}$ (unimolecular)
$\mathrm{H}_2+\mathrm{I}_2 \rightarrow 2 \mathrm{HI}$ (bimolecular)
$2 \mathrm{NO}+\mathrm{O}_2 \rightarrow 2 \mathrm{NO}_2$ (trimolecular)
Molecularity is the theoretical concept. It cannot be zero/non-integer
