The rate of diffusion of liquids is _ than gases.
Correct answer: A. Lower
- A. Lower
- B. Higher
- C. Equal to
- D. All of these options are correct
Explanation
Diffusion is the intermixing (movement) of molecules. When looking at diffusion you must look at two factors: forces of attraction and kinetic energy of molecules. Liquids have a stronger force of attraction than gases, and liquids have less KE than gases. This is because gas particles are further apart compared to liquid particles and move faster. This makes liquids have a lower rate of diffusion than gases.

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.
