Liquid-Vapor Equilibria in Mixtures: Ideal and Excess Chemical Potentials - Lecture 16

MIT OpenCourseWare via YouTube

Overview

Explore advanced thermodynamics concepts in this comprehensive lecture focusing on liquid-vapor equilibria in mixtures and related phenomena. Master fundamental principles including Raoult's law, dew and bubble lines, distillation processes, freezing point depression, and boiling point elevation. Delve into non-ideal mixtures, examining Duhem-Margules relations, ideal and excess Gibbs free energy, and chemical potentials. Progress through detailed explanations of mixture properties, activity coefficients, fugacities, and various models including Margules, Van Laar, and Lennard-Jones binary mixtures. Learn from Professor Gian Paolo Beretta's expert instruction, enhanced by detailed slides and timestamps for easy navigation through topics. For optimal learning efficiency, viewing at 1.5x speed is recommended.
