Factors Affecting Diffusion

• Which factors affect the rate of diffusion?

  Both
• How does temperature affect the rate of diffusion?

  Higher temperatures increase the rate of diffusion
• What happens to the rate of diffusion if the concentration gradient is steeper?

  The rate of diffusion increases
• How does surface area affect the rate of diffusion?

  Larger surface area increases the rate of diffusion
• Which of the following will speed up diffusion?

  A larger surface area
• What is the effect of a smaller concentration gradient on the rate of diffusion?

  It decreases the rate of diffusion
• Why does diffusion occur faster in gases compared to liquids?

  Molecules in gases move faster
• How does the thickness of the membrane affect the rate of diffusion?

  Thicker membranes decrease the rate of diffusion
• Which of the following factors would make diffusion slower?

  A thick cell membrane
• What happens when diffusion reaches equilibrium?

  The particles continue to move but there is no net movement
