This course has the objective of reviewing the basic concepts of thermodynamics with specific applications to processes involving phase equilibrium or equilibrium in chemical reactions. The course is divided in three parts. In the first part we will review the laws of thermodynamics, and the thermodynamic properties and phase behavior of pure substances. In the second part we will review the thermodynamic properties in mixtures and multiphase equilibria in non-reactive systems. In the last part of the course we will review the energy balance and equilibrium in chemical reactions. The evaluation will consist of a midterm at the end of the review section, and a final exam that will evaluate the last two parts of the course. This course also involves a term project where the student uses some of these concepts in a specific example related to his/her thesis project.
