Equal number of moles of O₂, Cl₂, and H₂ are enclosed in a container at room temperature. If the container leaks, then?
Answer: All will effuse out at the same time but with different rates
Explanation
All gases will start effusing at the same time, but the rate of effusion depends on their molar mass (Graham’s Law).
Lighter gases like H₂ effuse faster than heavier ones like Cl₂.
