2. the rate of diffusion is directly proportional to the concentration gradient. The greater the difference in concentration between two areas, the greater the rate of diffusion. Thus, when the gradient is zero, there will be no net diffusion, diffusion will only occur so long as a concentration gradient exists;

the rate of diffusion is indirectly proportional to resistance. In other ...
