Question
For a zero order reaction will the molecularity be equal to zero? Explain.

Solution
The molecularity of any reaction is the number of reacting species taking part in an elementary reaction. The zero molecularity means there is no reactant so the reaction does not occur. Therefore molecularity cannot be zero for a reaction.
