Question

is the space between the particles in the matter influence the speed of diffusion explain

Answer 1

Yes, it enfluences the speed of diffusion.

As we can see in the case of diffusion of any gas with any other gas. We observe that diffusion rate is very fast and occurs certainly this is only because if large intermolecular spaces between their particles. Since, solid do not have such large spaces so its diffusion rate is very much slow as compared to liquid or any gas.
