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

The molecularity of a reaction is defined as the count of molecules participating in an elementary reaction. This metric is crucial for elucidating a reaction's mechanism.
Step 2: Therefore, option (3) is the correct selection.
