Question

The number of molecules that react with each other in an elementary reaction is a measure of the:

• A. activation energy of the reaction
• B. stoichiometry of the reaction
• C. molecularity of the reaction
• D. order of the reaction

Hint:

Molecularity is the number of reactant molecules that collide in an elementary step to undergo a reaction.

Answer 1

The Correct Option is C

Step 1: Molecularity of a reaction refers to the number of molecules involved in an elementary reaction. It is a fundamental concept used to determine the mechanism of a reaction. 

Step 2: Thus, the correct answer is option (3).
