Adsorption (physisorption, chemisorption), Freundlich and Langmuir isotherms, catalysis, colloids, emulsions, and gels.
Freundlich isotherm: x/m = kP^(1/n), Langmuir isotherm: θ = (KP)/(1 + KP).
Misapplying adsorption isotherms; confusing colloids with true solutions or suspensions; neglecting surface energy in catalysis explanations.
Basics of bonding, intermolecular forces, and thermodynamics.
Understand the differences between physisorption and chemisorption; memorize and practice Freundlich and Langmuir isotherms for adsorption.
Solve 25-30 problems, including numerical calculations and conceptual questions on adsorption and colloids.
