Question

What are the factors that affect the rate of diffusion ?

Answer 1

Many factors affect the rate of diffusion such as :

(I) Density of the substance

(ii) Density or permeability of the medium

(iii) Temperature

(iv) Diffusion pressure

(v) Distance

Density increase reduces diffusion.

Increase in temperature causes an increase in diffusion.

Increase in temperature increases diffusion as the kinetic energy of particles increases.
