Question:

Assertion: Order and molecularity are always same.

Reason: Order is determined experimentally and molecularity is the sum of the stoichiometric coefficient of rate determining elementary step.

Options:

Assertion and Reason both are correct statements and reason is the correct explanation for assertion.

Assertion and Reason both are correct statements and reason is not the correct explanation for assertion.

Assertion is correct statement but reason is wrong statement.

Assertion is wrong statement but reason is correct statement.

Correct Answer:

Assertion is wrong statement but reason is correct statement.

Explanation:

Order and molecularity are not always same. They may be the same for bimolecular or trimolecular reactions.

Order is determined experimentally and molecularity is the sum of the stoichiometric coefficient of rate determining elementary step.
