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.

Correct option is D

The correct answer is (d) Both I and II.
· Statement I is correct because the rate of diffusion in liquids is indeed higher than that of solids. This is because particles in a liquid state have more kinetic energy than those in a solid state, allowing them to move more freely.
· Statement II is also correct as in the liquid state, particles are less tightly packed compared to solids, meaning there is more space between particles. This greater freedom of movement enables faster diffusion in liquids than in solids, where particles are closely packed and vibrate in fixed positions.
Information Booster:
· Diffusion: The process by which particles move from an area of higher concentration to an area of lower concentration.
· Rate of Diffusion: Liquids have a higher diffusion rate than solids because the particles in liquids can move past each other more easily than in solids.
· Solids: In solids, particles are tightly packed in a fixed structure, which restricts their movement and hence results in a slower rate of diffusion.
· Liquids: The particles are loosely bound compared to solids and can slide past each other, resulting in faster diffusion.
