Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Imagine a scenario where you increase the temperature of an agarose gel containing dye. Discuss how the change in temperature would affect diffusion and provide a mathematical rationale using the Arrhenius equation.

💡 Hint: Relate it back to molecular motion.

Challenge 2 Hard

Design an experiment to test how varying the viscosity of a medium affects diffusion rates of different sizes of dye molecules. Discuss the expected outcomes.

💡 Hint: Think about how size interacts with viscosity in liquids.
