Abstract

This course introduces the physical chemistry of Earth surface processes, focusing on thermodynamics, kinetics, and transport in low-temperature aqueous systems. It covers how chemical reactions are described at equilibrium and how real systems evolve when reactions are limited by rates and transport.

Objective

By the end of the course, students will be able to describe and quantify the physical and chemical processes that govern reactions in low-temperature aqueous systems. Specifically, they will be able to: Apply equilibrium thermodynamics to calculate chemical speciation, complexation, and mineral stability, including the construction of mineral stability diagrams, in aqueous systems. Predict how chemical systems respond to changes in composition, pH, and environmental conditions (e.g., temperature and salinity). Explain and apply reaction kinetics, including the derivation and use of rate laws for mineral dissolution, precipitation, and redox processes Explain surface reactions such as sorption and ion exchange, and their role in controlling chemical behavior in the environment. Analyze the interaction between chemical reactions and transport (diffusion and advection) in natural systems. Use and interpret simple numerical models to simulate how chemical systems evolve over time. Link molecular-scale processes to system-scale behavior in Earth surface and environmental settings.

Content

The course is organized into five thematic modules that move from equilibrium descriptions to time-dependent systems: 1. Aqueous Thermodynamics and Speciation: Chemical speciation, complexation, and non-ideal solution behavior in aqueous solutions. 2. Mineral Solubility and Stability: Thermodynamic limits of mineral dissolution and precipitation including saturation states and physical-chemical controls on mineral stability. 3. The Mineral – Water Interface: Surface reactions, including sorption and ion exchange in soils and sediments. 4. Reaction Kinetics: Rates of mineral reactions and redox processes, and how they control chemical change over time. 5. Transport – Reaction Coupling and Modeling: Interaction between chemical reactions and transport (diffusion and advection), explored through simple numerical models.
