Objectives

To develop the student’s skills for experimental work. This will be achieved through the accomplishment of physical chemistry experiments involving the determination of thermodynamic and kinetics parameters, analysis and interpretation of results and scientific reports writing.

Learning outcomes and competences

To develop the student’s skills for experimental work. To improve the student’s skills in presentation of scientific results and its discussion. To develop critical thinking, encouraging critical analysis of the experimental results obtained and to develop report writing skills.

Calculation formula of final grade

NLAB is the overall laboratory mark equal to the average of the laboratory marks obtained on the laboratory practical sessions.
NR1 and NR2 are the marks obtained on the written reports and oral presentations 1 and 2.
NRF is the mark obtained on the final written report.

The final mark (NF) is calculated according to:
NF = 0.40 × NLAB +  0.15 NR1 + 0.15 NR2 + 0.30 × NRF
