Rate of diffusion of a gas is

ADirectly proportional to its density
BDirectly proportional to its molecular mass
CDirectly proportional to the square root of its molecular mass
Dinversely proportional to the square root of its molecular mass
Correct Answer

Solution

Rate of diffusion of a gas is inversely proportional to the square root of its molecular mass

Hence, Option "D" is the correct answer.
