Question

when looking at your data from the effect of concentration on the rate of diffusion lab, what occurred to the rate of diffusion as time elapsed? multiple choice the rate of diffusion stayed the same for all three concentrations of potassium permanganate crystals the rate of diffusion decreased for only the lowest concentration of potassium permanganate crystals the rate of diffusion increased for all three concentrations of potassium permanganate crystals the rate of diffusion decreased for all three concentrations of potassium permanganate crystals the rate of diffusion increased for only the highest rate of concentration of potassium permanganate crystals

Explanation:

Diffusion is the movement of particles from an area of high - concentration to an area of low - concentration. As time elapses, the concentration gradient (the difference in concentration between two areas) decreases. Since the driving force for diffusion is the concentration gradient, the rate of diffusion decreases for all concentrations as the gradient lessens.

Answer:

the rate of diffusion decreased for all three concentrations of potassium permanganate crystals
