Question: Explain the three factors that affect the rate of diffusion, according to the provided notes.

Answer:
The three factors that affect the rate of diffusion are:

• 1. Concentration Gradient: The concentration gradient is the difference in concentration between two regions. A greater concentration gradient leads to a faster rate of diffusion.
• 2. Temperature: Temperature directly affects the kinetic energy of particles. Higher temperatures increase kinetic energy, causing particles to move more vigorously, which results in a faster rate of diffusion. Conversely, lower temperatures lead to slower diffusion due to reduced particle movement.
• 3. Particle Size/Molecular Weight: Smaller particles with lower molecular weight diffuse more quickly than larger particles. Larger particles have more mass and experience greater resistance, leading to slower diffusion rates.
