Which law states that the rate of diffusion or effusion of a gas is inversely proportional to the square root of its molar mass?
A. Boyle's law
B. Charles's law
C. Graham's law✓ Correct Answer
D. Gay-Lussac's law
💡 Solution & 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. Boyle's law and Charles's law describe pressure-volume and volume-temperature relationships respectively. Lighter gases travel faster through porous barriers than heavier gases due to this principle.
