Lecture 17 - Environmental Chemodynamics
See Lecture Schedule for
Delivery Date
Learning Objectives
- List the thermodynamic functions used to describe the
energy status of molecules in an environmental system.
- Understand the relationship of Gibb’s free energy and
chemical potential in the transfer or transformation of
chemicals in a system.
- Develop a basic understanding of fugacity and its role
in environmental transformations.
- Define activity and its relationship to concentration.
- Understand the concept of energy bookkeeping and the
relationship of Gibb’s free energy to enthalpy and entropy
in an phase transformation or chemical reaction.
- Develop a basic understanding of first order and psuedo-first
order chemical kinetics including integrated rate
expressions, half-lives and T dependence.
- Understand the compartment model of the ecosphere.
- Understand the partitioning of chemicals and how
partition constants are used in describing environmental
systems.
- Understand the basic approaches to modeling
chemodynamics and the usefulness and limitations of model
use.
