Question

Molecularity of the reaction 2NO+O2=2NO2

Answer 1

Answer : The molecularity of the reaction is 3.

Explanation :

Molecularity : It is equal to the total number of reactant molecules taking part in the balanced equation of a reaction. It is a theoretical concept.

The given balanced reaction is,

$2NO+O_2\rightarrow 2NO_2$

In this reaction, 2 NO molecules reacts with the 1 $O_2$ molecule.

Total number of reactant molecule = 2 + 1 = 3

Therefore, the molecularity of the reaction is 3.
