Question
Write molecularity of the following reaction:
2NO(g)+O2(g)→2NO2(g)
Advertisements
Solution 1
2NO+O2→2NO2
Molecularity of reaction = 3
Solution 2
The molecularity of the reaction is 3.
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,
2NO(g)+O2(g)→2NO2(g)
In this reaction, 2 NO molecules reacts with the 1 Oxygen molecule.Total number of reactant molecule = 2 + 1 = 3
Therefore, the molecularity of the reaction is 3.
