Solution

## Unimolecular reaction: A reaction in which only one reacting molecule is involved is known as a Unimolecular reaction.Example: Decomposition of ammonium nitrite.The chemical reaction can be depicted as: $2{\mathrm{NaNO}}_{3}\left(\mathrm{aq}\right)\to 2{\mathrm{NaNO}}_{2}\left(\mathrm{aq}\right)+{\mathrm{O}}_{2}\left(\mathrm{g}\right)$Bimolecular reaction:“A bimolecular reaction involves a simultaneous collision between two species.”Example: Dissociation of hydrogen iodide.The chemical reaction can be depicted as: $2{\mathrm{H}}_{2}\left(\mathrm{g}\right)+{\mathrm{I}}_{2}\left(\mathrm{g}\right)\to 2\mathrm{HI}\left(\mathrm{g}\right)$Thus, a reaction involving two different reactants can never be an unimolecular reaction.
