Semester: SEM2
Originating Department: Chemistry
Pre-requisites: N/A
   
Aims
This module covers several subject areas of physical chemistry: thermodynamics, kinetics, quantum mechanics, spectroscopy, and photochemistry. The aims are to


1. revised and extend the study of the 1st and 2nd laws of thermodynamics to chemical reactions,

2. study the basic ideas and factors affecting the rates of chemical reactions.

3. give an more advanced coverage in quantum mechanics.

4. reinforce some aspects of molecular spectroscopy.
Learning outcomes 
By the end of the module, students should be able to:

A. effectively apply thermodynamic principles.

B. discuss the rate of reaction and reaction mechanisms through studying kinetics of reactions.

C. demonstrate an understanding of the basic concepts of quantum mechanics.

D. apply Schrodinger equation to for translational, vibrational, and rotational motions.

E. apply molecular orbital (MO) theory to rationalise and make predictions of the bonding in molecules.

F. discuss spectroscopy as a result of energy transitions between atomic/molecular energy levels.

G. describe different decay processes of photo excited states and use the phenomena as quantitative analysis methods.

Method of teaching and learning 
The material presented at the lectures and its application for solving problems is supported by work in small group tutorials and interactive events. Students are expected to prepare the answers to tutorial problem questions and submit them before tutorials. Discussions during tutorials will focus on problems caused the most difficulties. Two summative tests will be introduced to monitor continuously student’s learning progress.
