The rate of diffusion or effusion is _ proportional to the square root of its density at constant temperature and pressure.

Correct answer: B. Inversely

  • A. Directly
  • B. Inversely
  • C. Equally
  • D. Highly

Explanation

The rate of diffusion or effusion is inversely proportional to the square root of its density at constant temperature and pressure. Diffusion is the process by which molecules spread from an area of higher concentration to an area of lower concentration, and effusion is the process by which gases escape from a container through a small opening.

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.
