Graham’s Law of Effusion
Name_______________________ Hr___
Formula:
1. What is the ratio of the speed of hydrogen molecules to that of oxygen
molecules when both gases are at the same temperatures?
2. At 300K, the velocity of oxygen molecules is 483m/s. What is the velocity
of xenon atoms at the same temperature?
3. Compute the relative rates of helium atoms to argon atoms. (How much
faster are helium atoms than argon atoms?)
4. Compute the relative rates of neon atoms to krypton atoms (How much
faster are neon atoms than krypton atoms?)
5. The velocity of helium atoms at 300K is 1370m/s. What is the speed of
radon atoms at the same temperature?
