Which of the following pairs of gases have the same rate of diffusion?
Correct answer: A. CO2 and N2O
- A. CO2 and N2O
- B. CO2 and CO
- C. NO2 and CO2
- D. CO2 and N2O4
Explanation
According to Graham's Law, the rate of diffusion or effusion is inversely proportional to the square root of molar mass. Both CO2 and N2O have the same mass (44). So, they have a similar rate of diffusion.

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.
