Assertion: A lighter gas diffuse more rapidly than a heavier gas.
Reason: At a given temperature, the rate of diffusion of a gas is inversely proportional to the square root of its density.

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:
A
Rate of diffusion of a gas is inversely proportional to the square root of the molecular weight of a gas . This is Grahm.s law of diffusion and vapour density of a gas is equal to half of its molecular weight .
