Equilibrium Partitioning of Organic Compounds

This lecture covers the concept of equilibrium partitioning of organic compounds among different environmental phases, focusing on liquid-liquid and gas-liquid systems. It explains the principles behind partition coefficients and how to calculate them using fugacity and molar concentration units. The instructor presents examples involving alachlor and benzene to illustrate the application of these concepts in real environmental scenarios. Additionally, the lecture introduces the tools and fundamental concepts from thermodynamics necessary to understand the equilibrium distributions of organic compounds. The discussion includes the chemical potential, Gibbs free energy, and the relationship between fugacity and chemical potential.
