• Explain the basics of Fick’s law and similarity to other rate-transfer processes

• Be able to predict binary diffusion coefficients for both gases and liquids

• Explain the physical significance of a mass-transfer coefficient

• Solve simple problems involving molecular diffusion, convection, and chemical reaction
