The rate of diffusion of hydrogen gas as compared to that of oxygen gas is:
Correct answer: B. 4 times
- A. 6 times
- B. 4 times
- C. one fourth
- D. one eighth
Explanation
Graham's law states that the rate of effusion or of diffusion of a gas is inversely proportional to the square root of its molecular weight. If you substite values in the formula given below, you will get the answer 4.So, rate of diffusion of hydrogen gas is four times faster than oxygen gas.

About Kinetic Molecular Theory
Kinetic molecular theory explains gases as rapidly moving particles separated by large distances, with negligible volume and negligible intermolecular attraction in the ideal model. It relates temperature to average kinetic energy and explains gas pressure, Boyle's and Charles's laws, diffusion, effusion and the conditions under which real gases deviate from ideal behavior.
