Chemical
Kinetics
Acid-base Reactions & The Carbonate System
|
| Overview |
| The
lectures for this week cover two topics. First, we
very briefly review some basic principles of chemical
kinetics (the study of the rates of chemical reactions). You
will be introduced to some of the most fundamental concepts
such as rate laws, reaction orders, temperature-dependence
of rates (the Arrhenius equation), and dissolution and
precipitation of minerals. Pay particular attention to the
concept of hyperbolic kinetics (the Michaelis-Menton
equation) as we will return to this concept when discussing
biodegradation of organic contaminants. Second, we
will review some basic concepts from acid-base theory,
receive a brief introduction to one of the most important
acid-base systems (the carbonate system), and learn to
graphically represent acid-base equilibria using a type of
diagram called a Bjerrum Plot. |
