1. Temperature: Higher temperatures generally increase the rate of diffusion as particles have more energy and move more quickly.

2. Concentration gradient: The greater the difference in concentration between two areas, the faster diffusion will occur.

3. Surface area: A larger surface area allows for more particles to come into contact with each other, increasing the rate of diffusion.

4. Size of particles: Smaller particles diffuse more quickly than larger particles as they can move more easily through a medium.

5. Medium: The type of medium through which diffusion occurs can affect the rate of diffusion. For example, diffusion occurs more quickly in liquids and gases compared to solids.

6. Distance: The distance over which diffusion occurs can also affect the rate of diffusion. Shorter distances generally result in faster diffusion.

7. Pressure: Higher pressure can increase the rate of diffusion as it forces particles closer together, increasing the likelihood of collisions and diffusion.

1. Concentration Gradient: The rate of diffusion is directly proportional to the concentration gradient, which is the difference in the concentration of the diffusing substance between two regions.

2. Surface Area: The rate of diffusion is proportional to the surface area available for diffusion. A larger surface area allows for more exchange of molecules.

3. Distance: The rate of diffusion is inversely proportional to the distance over which diffusion occurs. The shorter the distance, the faster the diffusion rate.

4. Temperature: The rate of diffusion increases with temperature. Higher temperatures increase the kinetic energy of molecules, making them move faster and diffuse more rapidly.

5. Viscosity: The rate of diffusion is inversely proportional to the viscosity of the medium. Viscosity is the resistance to flow within a fluid. Higher viscosity slows down the movement of molecules and reduces the diffusion rate.

6. Molecular Size and Shape: Smaller molecules diffuse faster than larger molecules. Additionally, molecules with irregular shapes diffuse more slowly than molecules with spherical shapes.

7. Electrical Charge: Charged molecules diffuse differently depending on their charge. Positively and negatively charged molecules are attracted to oppositely charged ions in the medium, which can alter their diffusion rates.

8. Membrane Permeability: The rate of diffusion through a membrane depends on the membrane's permeability. Permeable membranes allow substances to pass through more easily, while impermeable membranes block diffusion.

9. Pressure: The rate of diffusion is affected by pressure. An increase in pressure can force more molecules into a region, increasing the concentration gradient and speeding up diffusion.

10. Binding Affinity: If the diffusing molecule binds strongly to other molecules in the medium, its diffusion rate can be reduced. Binding affinity affects the concentration gradient and the availability of molecules for diffusion.
