Question

The high rate of diffusion in gases is due to the

• A. high intermolecular forces of attraction among the particles.
• B. high kinetic energy of the particles.
• C. restricted motion of particles.
• D. all of these.

Answer 1

The correct option is B high kinetic energy of the particles.

Diffusion is the process in which particles move from a region of higher concentration to a region of low concentration until the uniform concentration is achieved. In gases, the rate of diffusion is more due to the high kinetic energy of particles.
