General description and relevant information The subject focuses on the thermodynamics more directly related to the design of separation and/or reaction units . The main educational objectives are: Estimate the thermodynamic properties of pure substances and mixtures. To characterize a multiphasic or reactive system in equilibrium based on the state functions entropy and free energy. Generate and interpret the phase diagrams of pure substances and mixtures with multiple components. Determine the conditions of chemical equilibrium in homogeneous and heterogeneous reactive systems. Apply the previous concepts to the design of chemical processes.

  Description
Introductory activities Presentation of the content and organization of the subject, as well as its connection with previous and subsequent subjects. Review of the material available in the Moodle space.
Lecture Combination of lectures and case study through the introduction of the basic concepts, the discussion of examples and the completion of exercises in the classroom. Group or individual discussion meetings are expected to clarify concepts or methodologies. The student's dedication to study assignments is included to deepen the understanding of the concepts provided.
Problem solving, exercises in the classroom Sets of problems solved by the students, individually or in groups, and supervised by the teaching staff. This includes the individual work of the student derived from this activity. On conveniently communicated dates, problems made in groups will be collected.
Assignments Resolution of a practical case of application of Thermodynamics for the design of processes in the chemical process industry. Working in small groups, the concepts developed in the subject must be applied with criteria and in a real context.
Personal attention Meetings, individual or group, during attention hours to clarify specific aspects of the concepts provided.

Personalized attention
Description
Meetings, outside the classroom, individual or in small groups in order to discuss specific issues or problems. The attention hours will be communicated conveniently and the contacting channels informed in the Moodle space.

In the same way, a virtual room will be available to carry out meetings by remote videoconference with the same schedule. The link will be conveniently communicated in the Moodle space.

Other comments and second exam session

This subject presents specific pass conditions.

It is a necessary but not sufficient condition to pass the evaluation, regardless of any other consideration, to be able to interpret and generate binary phase equilibrium diagrams. In the final exam (5) or the 2nd call exam, the exercises used used to verify this condition will be indicated.

In the 2nd call, the contribution of the continuous evaluation part related to the resolution of problems, that is to say, sections 1 and 3 of the above description, will be maintained for a total of 10%. Therefore, the 2nd call exam, of a format similar to the description made in section 5, will represent 90% of the final mark.

During the tests, you can not have activated mobiles and it is completely prohibited to handle them during the test.

In any test, you can not use any external communication channel or you can connect to the network to do something that is not strictly allowed and informed in the exam.

Non accomplishment of these two previous rules entails the immediate suspension of the subject, regardless of the disciplinary consequences that may derive from.

Additionally, complementary instructions will be provided in each test, equally binding.
