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 :- In a multi-step reaction, the molecularity of overall reaction has no significance. Reason :- Molecularity of a reaction is always equal to order of reaction.

If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion.

If both Assertion & Reason are True but Reason is not a correct explanation of the Assertion.

If Assertion is True but the Reason is False.

If both Assertion & Reason are False.

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 .

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

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

If assertion is true but reason is false

If the assertion and reason both are false .

A : Order and molecularity of a reaction are always equal R : Complex reactions takes place is steps and fastest step determine the molecularity of reaction.

If both Assertion & Reason are true and the reason is the correct explanation of the assertion , then mark (1).

If both Assertion & Reason are true but the reason is not the correct explanation of the assertion , then mark (2).

If Assertion is true statement but Reason is false, then mark (3).

If both Assertion and Reason are false statements , then mark (4)
