Question 1

What does Fick's law state about the direction of flux?

  • It moves from low to high concentration
  • It moves from high to low concentration
  • It moves in all directions equally

💡 Hint: Think about where substances want to go.

Question 2

True or False: Higher viscosity increases the rate of diffusion.

  • True
  • False

💡 Hint: Consider what happens to syrup compared to water.

Challenge Problems

Push your limits with challenges.

Question 1

Describe a real-world pollution incident where diffusion played a key role. Analyze the factors involved and discuss how resistance affected the pollution's spread.

💡 Hint: Apply the concepts of flux and resistance to observable phenomena.

Question 2

Calculate the rate of diffusion for a hypothetical substance given its diffusion coefficient and concentration gradient. Discuss how changes in the concentration gradient affect the rate.

💡 Hint: Ensure you reflect on how concentration changes impact this calculation.
