The rate of diffusion of a gas having molar mass 32 as compared to H2 gas will be:
Correct answer: C. One fourth
- A. 6 times
- B. 4 times
- C. One fourth
- D. One eighth
Explanation
rateA/rateB = √molar mass B/molar mass A So, √2÷32 = √0.0625 = 0.25 or 1/4

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.
