Molecularity of a reaction__________________?
Correct answer: D. Both B. and C.
- A. Is always equal to the overall order of reaction
- B. May not be equal to the order of reaction
- C. Can't have a fractional value
- D. Both B. and C.
Explanation
Molecularity applies to an elementary reaction and is the number of participating species, so it is a positive integer. Reaction order may differ from molecularity and can be fractional, making both B and C correct.
