Why is rate of diffusion faster in gases?

Answer 1

In liquid, there is less space to move so collisions are more frequent between the molecules causing a slower diffusion rate. The opposite happens in gases. There is more space in gases. As a result, there are less collisions between the molecules causing a faster diffusion rate. Other factors that may have an affect on diffusion rates are temperature, mass of the molecule, volume/surface area, and medium used.

Answer 2

Diffusion in gases is quick because the particles in a gas move quickly. It happens even faster in hot gases.

In other states of matter diffusion cannot happen as fast because the particles move more slowly i.e. in a liquid

Diffusion doesn't happen at all in a solid because the particles are too close together. The only way they move is by vibrating.

Answer 3

Diffusion in gases is faster because gas particles have more kinetic energy, allowing them to move and spread out more rapidly compared to particles in liquids or solids. Additionally, gases have weaker intermolecular forces, resulting in less resistance to movement and faster mixing of molecules.

Thanks to my Junior year chemistry teacher Mrs.Xiomara Mendez!!U rock Miss!! SK

Answer 5

In a gas the particles can move about more freely and randomly. As a result, diffusion in gases happens much faster than that in liquids. :)

Answer 6

diffusion is directly proportional to the free movements of the substance and gases have a higher entropy and this free movement of molecules makes diffusion faster.

Answer 7

Rate of diffusion of gases is faster than liquids or solids because of the lack of intermolecular forces holding gas molecules together, and thus the faster movement of the molecules.

Answer 8

The molecules in a gas are very distant from each other.

Answer 9

The density of gases is very low.
