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.

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

If both assertion and reason are true and reason is the correct explanation of assertion.

If both assertion and reason are true but reason is not the correct explanation of assertion.

If assertion is true but reason is false.

If both assertion and reason are false.

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.

If both assertion and reason are true and reason is the correct explanation of assertion.

If both assertion and reason are true but reason is not the correct explanation of assertion.

If assertion is true but reason is false.

If both assertion and reason are false.
