Question

Given below are two statements, one is labelled as Assertion A and the other is labelled as Reason R
Assertion (A) : The order of a reaction can have fractional value.

Reason (R) : The order of a reaction cannot be written from balanced equation of a reaction.

In the light of the above statements, choose the correct answer from the options given below

• A. Both Assertion and Reason are true and Reason is the correct explanation of Assertion.
• B. Both Assertion and Reason are true but Reason is not the correct explanation of Assertion.
• C. Assertion is true but Reason is false.
• D. Both Assertion and Reason are false.

Answer 1

Answer: (B)

Both Assertion and Reason are true but Reason is not the correct explanation of Assertion.

Answer 2

It is an experimentally determined value and depends upon the concentration change of reactant. It changes with pressure, temperature and concentration and it can have the fractional value.
