Question

What is the molecularity of the following elementary reaction?

Answer 1

Answer : The correct option is, (B) bimolecular

Explanation :

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

The given balanced chemical reaction is,

$NH_2Cl(aq)+OH^-(aq)\rightarrow NHCl^-(aq)+H_2O(l)$

The number of reactants molecules taking part in the balanced equation of a reaction are, $NH_2Cl$ and $OH^-$.

In this reaction, 1 $NH_2Cl$ molecules reacts with the 1 $OH^-$ molecule.

Total number of reactant molecule = 1 + 1 = 2

The molecularity of the reaction is 2 that means, the elementary reaction is bimolecular.

Hence, the correct option is, (B) bimolecular
