Final answer:
The rate of diffusion is influenced by the concentration gradient, surface area, and distance traveled. Other factors such as temperature can also affect diffusion.
Step-by-step explanation:
The rate of diffusion between two points in a solution and between two sides of a membrane is influenced by several parameters. One important parameter is the concentration gradient, which is the difference in concentration between the two points or sides. The greater the concentration gradient, the faster the rate of diffusion.
Another parameter is the surface area available for diffusion. A larger surface area allows for more molecules to diffuse, increasing the rate of diffusion.
The distance the molecules must travel is also a factor. The shorter the distance, the faster the rate of diffusion. Other factors, such as temperature and cohesive and adhesive forces, can affect the rate of diffusion as well.
