A chemist needs to determine the diffusion rate of a solute in a liquid under non-uniform concentration conditions. Describe how Fick’s laws might apply and detail the calculations involved.
💡 Hint: Focus on the different conditions when applying each law.
In an experiment involving a cylindrical tube, molasses is allowed to diffuse in water. Given the necessary parameters, calculate the time it would take for a certain concentration to be reached using Fick’s laws.
💡 Hint: Set up your equations properly before solving them.
