Question

Explain factor affecting rate of diffusion in chemistry

Answer 1

Answer:

temperature, concentration gradient, size of the molecule, viscosity of the media, and the distance between the two points where diffusion happens

Explanation:

• Temperature increases the kinetic energy of the molecule so it moves faster and hence the rate of diffusion increases.

• the more the concentration gradient the higher the driving force of the process and hence the higher the rate of diffusion.

• the more the size of the molecule the higher the inertia it has so the less the rate of diffusion.

• the more the viscosity of the medium the more difficult it is for the molecule to move, the less the diffusion rate.

• the bigger the distance between the two points of diffusion the more time it needs for the molecule to arrive, and hence the less the rate of diffusion.
