Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Consider a scenario where the concentration of a substance is doubled. How would this affect the diffusion flux according to Fick's First Law? Use the formula to explain.

💡 Hint: Reflect on the effects of changing concentrations.

Challenge 2 Hard

If you were to conduct an experiment to measure diffusion coefficients at varying temperatures, what approach would you take and how would you expect D to change? Discuss your observations.

💡 Hint: Consider the relationship between energy and movement.
