Why can't molecularity of any reaction be equal to zero?

Text Solution

Verified by Experts

The correct Answer is:
N/a
Molecularity of the reaction is the number of molecules taking part in an elementary step For this we require at east a single molecule leading to the value of minimum molecularity of one. Hence molecularity of any reacton can never be equal to zero.

What is meant by molecularity of a reaction ? Why the molecularity of a reaction rarely exceeds three?

Assertion : Molecularity greater than three is not observed. Reason : The overall molecularity of complex reaction is equal to molecularity of the slowest step.

Assertion : Complex reaction takes place in different steps and the slowest step determines the rate of reaction. Reason : Order and molecularity of a reaction are always equal.
