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

A

Both Assertion and Reason are true and Reason is the correct explanation of the Assertion.

B

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

C

Assertion is true but Reason is wrong .

D

Both Assertion and Reason are wrong .

Text Solution

Verified by Experts

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