Factor affecting diffusion

Several factors affect the rate of diffusion:

1. Temperature: An increase in temperature provides particles with more kinetic energy, causing them to move faster and collide more frequently, thus increasing the rate of diffusion.
2. Concentration Gradient: The steeper the concentration gradient (the larger the difference in concentration between two areas), the faster the net movement of particles from the region of higher concentration to the region of lower concentration.
3. Surface Area: A larger surface area available for diffusion allows more particles to move across simultaneously, leading to a faster overall rate of diffusion.
4. Particle Size/Mass: Smaller and lighter particles diffuse more rapidly than larger and heavier particles because they have less inertia and can move more easily through the medium.
5. Distance/Thickness: The shorter the distance over which diffusion needs to occur, or the thinner the membrane through which particles are diffusing, the faster the rate of diffusion.
