Note: In the following questions a statement of assertion followed by a statement of reason is given. Choose the correct answer out of the following choices.

Assertion : Order of the reaction can be zero or fractional.

Reason : We cannot determine order from balanced chemical equation

Order of a reaction is an experimental quantity. Thus, it can be zero or fractional.

We cannot determine order from a balanced chemical reaction as a chemical reaction hardly completes in a single step.

Thus, both assertion and reason are correct but the reason is not the correct explanation of assertion.
