Shorter distances increase the rate

Greater distances increase the rate

|
|
Distance does not affect the rate
|
Detailed explanation-1: -distance-if the diffusion distance is small, diffusion happens faster because the particles do not have as far to travel.
Detailed explanation-2: -Diffusion is rapid over very short distances, and slow over longer distances.
Detailed explanation-3: -The greater the difference in concentration, the quicker the rate of diffusion. The higher the temperature, the more kinetic energy the particles will have, so they will move and mix more quickly. The greater the surface area, the faster the rate of diffusion.
Detailed explanation-4: -Why is diffusion effective only over short distances? Because the longer the distance between two concentrations the slower molecules diffuse. Because the rate of diffusion is affected by temperatures which vary over long distances.
Detailed explanation-5: -The rate of diffusion is affected by the concentration gradient, membrane permeability, temperature, and pressure.
