Question

find molecularity of the reaction. 2No+O2 gives 2No2

Answer 1

. 2No+O2=>2No2
molecularity of reaction=3

Answer 2

Explanation:

The total number of reactant atoms, species or molecules taking part in a reaction is defined as the molecularity of a reaction.

The given reaction is as follows.

     $2NO + O_{2} \rightarrow 2NO_{2}$

Here, two NO molecules react with one molecule of $O_{2}$.

Therefore, the molecularity of the reaction is 2 + 1 = 3.
