Chemical Thermodynamics

Recommended Prerequisites

Calculus I and II, General Chemistry.

Teaching Methods

The teaching is done in both  theoretical and practical sessions. The lectures are expository but also include examples and exercises where the knowledge acquired is applied. The practical classes are intended for problem solving, and the work and group discussion will be encouraged. In practical classes there will be also methodologies using virtual applications developed in JavaScript.

Learning Outcomes

General objectives:

  Acquisition of knowledge related to the calculation of thermodynamic properties in fluid phase systems, dominant in chemical processes.

Specific objectives:

a) to know how to calculate variations of thermodynamic properties in physical transformations;

(b) to know how to calculate an apply the equilibrium properties of pure substances and mixtures;

(c) to develop knowledge in the field of thermodynamic properties related to systems consisting of pure substances and mixtures necessary for the application in the design of engineering installations.

(d) to seek for the development of critical thinking and autonomous learning in those domains.

Work Placement(s)
