Question 1
What does Fick’s Law describe?
- Movement of particles from high to low concentration
- Movement of particles against concentration
- Random movement of particles
💡 Hint: Think about how pollutants spread in streams.
Question 2
The diffusion coefficient is inversely related to which of the following?

Challenge Problems
Push your limits with challenges.
Question 1
Consider a pollutant leaking into a lake. If the diffusion coefficient of this pollutant in water is known, how could you estimate its concentration over time?
💡 Hint: What equations relate to the concentration gradient here?
Question 2
If two substances differ significantly in molecular weight, how would this affect their respective diffusion coefficients in air?
💡 Hint: Remember how molecular weight relates to diffusion rates.
