Final answer:
The rate of diffusion is influenced by factors such as molecular size, temperature, solution density, and distance traveled.
Step-by-step explanation:
Diffusion is the process by which particles move from an area of higher concentration to an area of lower concentration. The rate of diffusion is influenced by several factors, including molecular size, temperature, solution density, and distance traveled.
Molecular size: Smaller molecules diffuse more quickly than larger molecules because they can more easily move between other molecules in the medium.
Temperature: Higher temperatures increase the kinetic energy of particles, causing them to move more quickly and diffuse faster.
Solution density: A higher density of particles in the solution can slow down diffusion because there are more obstacles for the particles to move through.
Distance traveled: Longer distances require more time for particles to diffuse, resulting in a slower rate of diffusion.
