What particle diffused the farthest, potassium permanganate or methylene blue? what was the factor in the difference in diffusion rates?

Diffusion is a physical process where particles move from higher concentration to lower concentration. The particles which diffuses could be liquid, gas and solid.

Methylene blue has a high molecular weight compare to potassium permaganate , so the lighter molecules diffuses more rapidly than heavier molecules.

Temperature, density of the diffusing particles , medium of diffusion and concentration gradient these factors affect the diffusion rate.

your answer is true

i am 100% sure
