Which of the following statement is correct regarding rate of diffusion of liquids? I. Rate of diffusion of liquids is higher than that of solids. II. This is due to the fact that in the liquid state, particles move freely and have greater space between each other as compared to particles in the solid state.

Explanation

Liquids naturally exhibit a much higher rate of diffusion than solids because their constituent particles are not locked into a rigid, structured lattice. The intermolecular forces in liquids are weaker, allowing molecules greater translational freedom to slide past one another and mix.
