| Assertion: Molecularity has no meaning for a complex reaction. |
| Reason: The overall molecularity of a complex reaction is equal to the molecularity of the slowest step. |
| Read the assertion and reason carefully to mark the correct option out of the options given below: |
A) If both assertion and reason are true and the reason is the correct explanation of the assertion.
B) If both assertion and reason are true but reason is not the correct explanation of the assertion.
C) If assertion is true but reason is false.
D) If the assertion and reason both are false.
E) If assertion is false but reason is true.
Correct Answer: B
Solution :
[b] Molecularity of a reaction can be defined only for an elementary reaction because complex reaction does not take place in one single step and it is almost impossible for all the total molecules of the reactants to be in a state of encounter simultaneously.
