Two molecules are diffusing in a water solution held at the same temperature T. Molecule A has three times the mass of molecule B. Molecule A has also a mean free path that is half that of molecule B. Both need to diffuse over the same distance (Xeff). How do the diffusion speeds compare? (Express your answer in terms of a “A over B” ratio).
