Assertion (A) Order of the reaction can ...

Assertion (A) Order of the reaction can be zero or fractional.
Reason (R) We cannot determine order from balanced chemical equation.

A

Both assertion and reason are correct and the reason in correct explanation of assertion.

B

Both assertaion and reason are correct, but the reason does not explain essertion

C

Assertion is correct but reason is incorrect

D

Both assertion and reason are incrrect.

Text Solution

Verified by Experts

The correct Answer is:
B
Both assertion and reason are correct, but the reason is not the correct explaration of assertion.
Order of reaction can be zero or fractional as order of reaction is directly related to sum of power of reactants . Reason is a correct statement but not correct explain .
