How is rate of diffusion of a gas proportional to the density of the gas?
STATEMENT-1 : A lighter gas diffuses mor rapidly than a heavier gas. STATEMENT-2 : At a given temperature, the rate of diffusion of a gas is inversely proportional to density.
Assertion: A lighter gas diffuses more rapidly than heavier gas. Reason: At a given temperature, the rate of diffusion of a gas is inversely proportional to the square root of its density.
