Assertion: Effusion rate of oxygen is smaller than nitrogen.
Reason: Molecular size of nitrogen is smaller than oxygen.

A

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

B

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

C

If assertion is true but reason is false.

D

If assertion is false but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
C
Assertion is true but reason is false because of effusion rate `prop (1)/(sqrt(M))` (molecular weight) but it does not depend on molecular size.
