As we learnt in

Molecularity -

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.

- wherein

Description:

NH_{4}NO_{2}\rightarrow N_{2}+2H_{2}O (unimolecular)

H_{2}+I_{2}\rightarrow 2HI (bimolecular)

2NO+O_{2}\rightarrow 2NO_{2} (trimolecular)

Molecularity is the theoretical concept. It cannot be zero/non-integer

 

 A reaction involving two different reactants can never be unimolecular reaction.

Option 2)

first order reaction

This option is incorrect

Option 3)
