Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

If the mass of a glucose solution in a dialysis bag increases by 5 grams over 30 minutes with an area of 10 cm² and ΔC of 0.1 mol/L, calculate the permeability coefficient.

💡 Hint: Make sure to convert minutes to seconds correctly for time.

Challenge 2 Hard

Design an experiment to test the impact of temperature on permeability with two different setups. Discuss the expected outcomes.

💡 Hint: Think about how changing temperatures influence kinetic energy.
