Graham's Law of diffusion relates rate of diffusion to:
A
Pressure only
B
Temperature only
C
Molar mass directly
D
Square root of molar mass
Correct Answer: Option D — Square root of molar mass
Explanation:
Graham's Law states that the rate of diffusion or effusion of a gas is inversely proportional to the square root of its molar mass, explaining why lighter gases diffuse faster than heavier ones.
