Question

why is the rate of diffusion in solids minimum and in gases maximum​

Answer 1

Answer:

As the intermolecular forces of attraction are most in solids so solids diffuse slower whereas the intermolecular forces of attraction are least in gases so gases diffuse the fastest.

Answer 2

Answer:

It is due to the less kinetic energy of solids. The molecules of solids are very tightly packed which causes the molecules to not leave the rigid structure and diffuse with other materials.

The molecules of gases are free to move so they diffuse easily.
