This course focuses on thermodynamics for high temperature processes involving chemical reactions. This course starts with review on the first to third laws of thermodynamics including enthalpy, heat capacity, entropy, Gibbs energy, etc., followed by the topics such as the chemical potential and the Gibbs phase rule, the latter being applied to phase diagrams and also systems involving various chemical reactions. Finally, the concept of activity is introduced along with standard states for components in gas and condensed phases, the latter including Raoultian, Henrian and 1mass% Henarian activities. By combining lectures and exercises, the course enables students to understand and acquire the fundamentals of chemical equilibrium calculation for systems involving various chemical reactions.
Thermodynamics is a basis for other courses provided in Graduate Majors 'Energy Science and Engineering' and 'Materials Science and Engineering' and is also very important for research and development of high temperature materials and processing. For example, the second law defines the maximum efficiency of heat engine. The Gibbs energy change predicts the maximum work generated by electrochemical cells and also predicts whether or not some reaction occurs at certain condition. A reaction which is not expected to occur thermodynamically will never occur. Thermodynamics should be useful to your own research as well. Students are also expected to understand the backgrounds against which the concepts such as enthalpy, Gibbs energy, activity and so on were created in addition to how to use them.
By the end of this course, students will be able to:
1) Explain the first to third laws of thermodynamics and understand the difference between internal energy and enthalpy.
2) Explain the physical meaning of Gibbs energy change in relation to the second law of thermodynamics.
3) Calculate the enthalpy, entropy and Gibbs energy change of reactions using molar heat capacity data and so on.
4) Understand the concept of the chemical potential and derive the Gibbs phase rule.
5) Calculate the number of degrees of freedom and specify the intensive valuables which are required to keep the system at equilibrium.
6) Explain the concept of activity and its relation with the equilibrium constant and also explain the relation between the equilibrium constant and the standard Gibbs energy change.
7) Understand the difference between Raoultin, Heanrian and 1mass% Henrian activities and apply them to chemical equilibrium calculations.

At the beginning of each class, solutions to exercise problems that were assigned during the previous class are reviewed. Towards the end of class, students are given exercise problems related to the lecture given that day to solve. To prepare for class, students should read the course schedule section and check what topics will be covered. Required learning should be completed outside of the classroom for preparation and review purposes.
