1. Graham's Law of Effusion states that the rate of effusion of a gas is inversely proportional to the of the square root of its molar mass.
2. Effusion is the process by which gas particles escape through a small opening into a .
3. Lighter gas molecules effuse than heavier gas molecules.
1. Which of the following gases would effuse the fastest at the same temperature and pressure?
O₂ (Oxygen)
N₂ (Nitrogen)
He (Helium)
CO₂ (Carbon Dioxide)
1. If it takes 20 seconds for 1.0 L of hydrogen gas to effuse, how long would it take for 1.0 L of oxygen gas to effuse under the same conditions? (Molar mass of H₂ = 2.02 g/mol, O₂ = 32.00 g/mol)
1. Graham's Law is applicable to both effusion and diffusion.
True
False
1. Explain how Graham's Law of Effusion can be used in real-world applications, such as separating isotopes.
