Prerequisites

It is recommended to have obtained the fundamental knowledge of the subjects Balance in Chemical Engineering, Chemical Balance and Organic Chemistry.

Objectives and Contextualisation

The objectives of the Chemical Kinetics course are to acquire and consolidate the fundamental concepts of kinetic, stoichiometry and reaction mechanisms as well as homogenous kinetics and heterogeneous catalytic kinetic. However, it is intended to acquire the skills specified in this teaching guide.

Competences

  • Analyse, evaluate, design and operate the systems or processes, equipment and installations used in chemical engineering in accordance with certain requirements, standards and specifications following the principles of sustainable development.
  • Apply relevant knowledge of the basic sciences, such as mathematics, chemistry, physics and biology, and the principles of economics, biochemistry, statistics and material science, to comprehend, describe and resolve typical chemical engineering problems.
  • Apply scientific method to systems in which chemical, physical or biological transformations are produced both on a microscopic and macroscopic scale.
  • Demonstrate knowledge of the different reaction, separation and processing operations for materials, and transport and circulation of fluids involved in the industrial processes of chemical engineering.
  • Develop personal work habits.
  • Develop thinking habits.
  • Understand and apply the basic principles on which chemical engineering is founded, and more precisely: balances of matter, energy and thermodynamic momentum, phase equilibrium and kinetic chemical equilibrium of the physical processes of matter, energy and momentum transfer, and kinetics of chemical reactions
  • Work in a team.

Assessment

Process and evaluation activities programmed
The subject consists of the following evaluation activities:
1. Seminars and tests that can be evaluated
- First evaluable test PA1. Individual exercise 5% of the note.
- Second evaluated test PA2. Evaluable seminar, problem-based learning, problem solving in a collaborative way from individual pre-based work based on bibliographic examples. 10% of the mark of the subject
- Third test evaluable PA3. Submission of written work done in groups, carried out on a scientific article. Peer evaluation. 10% of the mark of the subject.
- Fourth PA4 assessable test. Seminar evaluable. 5% of the mark of the subject.
- Fifth assessable activity PA5. Flipped classroom 5% of the mark of the subject.
2. Partial examinations
- First partial exam EP1 on Topics 1 and 2. 35% of the mark of the subject
- Second partial exam EP2 on Lessons 3 and 4. 30% of the mark of the subject.
3. Entry Ticket
At the beginning of some classes fast tests will be made about the knowledge acquired in the previous classes. Success in these tests will result in a 5% bonus in the course mark.
Programming of evaluation activities
The scheduling of the assessment activities will be given on the first day of the subject and will be made public through the Virtual Campus. The following guidance is scheduled:
- PA1 week 3 of the subject
- PA2 week 5 of the subject
- EP1 week 8 of the subject
- PA3 week 11 of the subject
- PA4 week 13 of the subject
- PA5 week 15 of the subject
- EP2 June, once the classes have finished
 
Recovery process
The recovery of the subject will be done through a synthesis examination of the syllabus corresponding to the entire subject. Only those students with a minimum mark of 3 in the continuous assessment will be entitled to the recovery.
Procedure for the review of qualifications
For each assessment activity, a place,date and time of revision will beindicated in which the student will be able to review the activity with the teacher. In this context, claims can be made about the activity note, which will be evaluated by the teachers responsible for the subject. If the student does not submit to this review, this activity will not be reviewed later.
Qualifications
Honor enrollments Granting an honorific matriculation qualification is a decision of the faculty responsible for the subject. The regulations of the UAB indicate that MH can only be awarded to students who have obtained a final grade of 9.00 or more. It can be granted up to 5% of MH of the total number of students enrolled.
A student will be considered non-evaluable (NA) if it has not been presented in a set of activities whose weight equals to a minimum of two thirds of the total grade of the subject.
Irregularities by the student, copy and plagiarism
Notwithstanding other disciplinary measures deemed appropriate, the irregularities committed by the student that can lead to a variation in the rating of an evaluation act will be graded with a zero. Therefore, copying, plagiarizing, cheating, copying, etc. In any of the assessment activities it will imply suspending it with a zero. Assessment activities qualified in this way and by this procedure will not be recoverable. If it is necessary to pass any of these assessment activities to pass the subject, this subject will be suspended directly, without opportunity to recover it in the same course.
