Challenge Problems
Push your limits with challenges.
Question 1
If a chemical is diffusing in a medium and the concentration gradient is high, what can you infer about the diffusion rate? Explain your reasoning.
💡 Hint: Relate it back to the role of the concentration gradient.
Question 2
Calculate the mass flux if the concentration gradient is 0.05 kg/m³ over a distance of 0.1 m, given that diffusivity is 1.2 m²/s.
💡 Hint: You need to apply the law correctly and keep track of negative signs.
