Read each question carefully and answer to the best of your ability. Show all work for calculations.
1. Graham's Law of Effusion states that the rate of effusion of a gas is inversely proportional to the square root of its .
2. Effusion is the process where gas particles escape through a tiny .
3. Lighter gases effuse than heavier gases.
4. Which of the following gases would effuse the fastest?
O2 (Oxygen)
H2 (Hydrogen)
CO2 (Carbon Dioxide)
N2 (Nitrogen)
5. If a gas has a molar mass of 4 g/mol, and another gas has a molar mass of 16 g/mol, how much faster will the lighter gas effuse?
2 times faster
4 times faster
8 times faster
16 times faster
6. Explain the difference between effusion and diffusion.
7. A gas effuses through a porous barrier at a rate of 0.50 mol/s. Another gas effuses through the same barrier at a rate of 0.25 mol/s. If the molar mass of the first gas is 16 g/mol, what is the molar mass of the second gas?
8. Graham's Law applies to gases at very high pressures.
True
False
9. The rate of effusion is directly proportional to the square root of the molar mass.
True
False
