Question

Molecularity of reaction

• A. Always equal to the overall order of the reaction
• B. Always greater than the overall order of the reaction
• C. Always smaller than the overall order of the reaction
• D. Cannot have a fractional value

Hint:

Molecularity is defined only for elementary reactions and is always an integer.

Answer 1

The Correct Option is D

Molecularity is the number of molecules involved in an elementary step and must be a whole number.
Order of reaction can be fractional, but molecularity cannot.
