After completing this chapter, you will be able to:
Explain the kinetic theory interpretation of diffusion in gases as due to random molecular motion and the basic equations needed for prediction of binary diffusivity.
Calculate the value of diffusion coefficients in binary gas mixtures and describe the relationship between the diffusion coefficient and the temperature and pressure.
Outline the concepts behind Einstein’s model for diffusion of dilute solutes in liquids.
Identify the complexities associated with diffusion and concentration effects on diffusion coefficients, especially in liquids.
Associate the effects of pore structure and pore diameter with diffusivity of fluids in porous ...
