What is the molecularity of the following elementary reaction?

nh2cl(aq) + oh-(aq) > nhcl-(aq) + h2o(l)

a) unimolecular

b) bimolecular

c) termolecular

d) tetramolecular

e) the reaction order must be known before molecularity can be determined.

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,

The number of reactants molecules taking part in the balanced equation of a reaction are, and .

In this reaction, 1 molecules reacts with the 1 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

cytokinesis is the splitting of a cell membrane to form 2 identical daughter cells. it's similar to mitosis as both cells have identical copies of dna and cytokinesis is a step in the mitotic cycle.
