Factors affecting Diffusion

Question 1

How does distance affect the rate of diffusion?

Answer 1

• The greater the distance that needs to be travelled, the slower the rate of diffusion

Question 2

How does temperature affect the rate of diffusion?

Answer 2

• The higher the temperature, the more movement of the molecules (more kinetic energy -> more frequent collision) , the faster the rate of diffusion

Question 3

How does substance affect the rate of diffusion?

Answer 3

• A substance with a greater mass has a lower diffusion rate

Question 4

How does concentration affect the rate of diffusion?

Answer 4

• The greater the difference in concentration, the faster the rate of diffusion.
