Answer #1

We know that molecularity is the number of species reacting to form new species in a elementary step.

Molecularity can neither be negitive or 0 or fractional.

It will always be a positive whole number.

So in first reaction there is only 1 reacting species. So unimolecular reaction

In 2nd reaction there are 2 species reacting hence it is called bimoleculer reaction.

Hence option 3rd is correct.
