Goals:

This course is designed to teach students the principles of

thermodynamics in a geochemical context. The concepts are

provided with examples for the entire range of pressure and

temperature conditions from magmatism to weathering. The

course is intended to provide the necessary background for

more advanced courses in petrology, geochemistry, mineral-

melt equilibria and aqueous geochemistry.

 

 

Prerequisites:

The students are expected to complete the Chemistry courses (Chem 111 & Chem 112)

 

 

 

Topics:

1.Fundamental Concepts (systems, states, processes, equilibrium, state variables)

 

2. Laws of Thermodynamics

3.1. Zeroth Law (introducing temperature)

3.2. First Law (introducing energy, work, heat)

3.3. Second Law (introducing entropy)

3.4. Third Law (absolute entropy)

                          3.5. Enthalpy (heat of reaction, heat of formation, heat capacity)

                          3.6. Gibbs Free Energy,  Clausius and Clausius-Clapeyron equations

 

3. Thermodynamics of  Solutions

    (concentration units,chemical potential,activity-fugacity, Raoult’s Law, Henry’s Law,

     mean vs. individual ionic activities, ionic strength, Debye-Huckel equation)

 

4. Phase Equilibria and Phase Diagrams

   (phase rule, one-component, two-component, three-component systems, solid

   solutions)

 

5. Equilibrium Constant

    (law of mass action, change with temperature)

 

6. Mineral-Solution Equilibria

  (ion activity product and saturation index)

 

7. Oxidation-Reduction Reactions

   (partial-pressure and Eh-pH diagrams)

Course Objectives:

 

  1. Emphasize the basic principles of thermodynamics.
  2. Describe the basic principles of thermodynamics in a geochemical context providing examples for the application of these principles to the natural systems of geological concern.
  3. Develop students’ ability to apply a quantitative reasoning to geologic problems.
  4. Develop students’ ability to apply an integrated knowledge of maths, chemistry, physics, mineralogy and geology to the solution of geochemical problems.
  5. Provide students with a background for more advance courses in petrology and aqueous geochemistry.

 

GRADING:

 

2 Midterm Exams (20% each)

1 Final Exam (30%)

*Homework Assignments (30%)

 

Homework Assignments will consist of a total of about 6 Sets of Problems (each set containing about 3 or 4 problems). Homeworks are assigned to Student Teams that will consist of 3 to 4 students. Grading of assignments for each team will be reflected in the grading of the students making up the team. Maintanance of colloboration and participation of each student in team work is the responsibility of the students making up the team (you will be working in colloboration for assignments but remember that you will be alone during the exams). Assignments should be turned in due time; later submissions will not be accepted (not be graded).
