उत्तर
Molecularity has no meaning for complex reactions.
Explanation:
The order of a reaction is an experimental quantity. It can be zero and even a fraction, but molecularity cannot be zero or a non-integer. Order is applicable to elementary as well as complex reactions, whereas molecularity is applicable only for elementary reactions. For complex reaction, molecularity has no meaning.
