What is the ratio of the diffusion rates of Cl₂ and O₂? Rate Cl₂ : O₂ = _______

Question

Quizplus · Accepted Answer

The diffusion rate is directly proportional to the square root of the molar mass. The molar mass of Cl₂ is roughly twice that of O₂, so its diffusion rate would be roughly √2 times slower. Therefore, the ratio of the diffusion rates of Cl₂ and O₂ would be approximately 1/√2 or 0.71. The closest answer choice to this is E, which is 0.67, making it the best choice.
