Lecture
This lecture discusses the mechanisms of gas/particle partitioning of inorganic compounds, including reactions forming condensible products. It covers examples of reactions among inorganic compounds and their condensible products, such as NH3(g) + HCl(g) = NH4Cl(s). The lecture also explores the framework of gas/particle partitioning of organic compounds, oxidation of reactive organic gases forming condensible products, and the formation of secondary organic particulate matter. It delves into the concepts of aerosol water content, photochemical production of OH, and nitrate aerosols. The lecture further examines the dynamics of mass transfer in aqueous and gas phases, conditions for phase equilibria, chemical potential as a driving force, excess Gibbs free energy, and activity coefficients in electrolyte solutions.
