Which Dye Used In The Diffusion Experiment Diffused Fastest?

Which Dye Used In The Diffusion Experiment Diffused Fastest? Potassium Permanganate is approximately half the molecular weight of Methylene Blue and diffuses more rapidly than Methylene Blue, resulting a slightly larger radius for the Potassium Permanganate dye spot than for Methylene Blue. Which dye do you think diffused faster through the agar and why? Potassium
