1st Cycle Studies
Recommended Prerequisites
Understanding and use of concepts in chemistry, apply knowledge acquired to solve problems in new situations. Good knowledge of English.
Teaching Methods
In the curriculum the discipline Chemistry corresponds to 6 credit units and a fourteen-week semester, the total number of predicted classes will be 28 lectures (3 hours per week) and 14 theoretical-practical classes (1 1/2 hours per week). Teaching methods consist of classes: theoretical, theoretical-practical and practical in order to attain the aim global learning
Theoretical and theoretical-practical evaluation: written questions.
Learning Outcomes
The objective of the discipline of Chemistry is to give to the students the opportunity to obtain knowledge in an area with many applications, in particular with regard to the study of mechanisms of reactions in solution.
The program objectives are:
1. Emphasize the principles necessary for understanding the nature of the chemical processes and reactions in solution solution.
2. Study the reactions kinetics and mechanism.
The extension given to each of these chapters is displayed in the program.
