Rationale and Purpose of the Module:
i. To facilitate students in understanding the fundamental thermodynamic laws and functions that rule a process of change in a physical chemical system.
ii. To provide students with requisite knowledge of analysing physical chemical systems, such as the phase transformation of a pure substance, the mixing and phase transformation of two components, using thermodynamic and derived thermodynamic functions.
iii. To familiarise the students with the phase diagrams and the use of these to analyse the above-mention physical chemical system.
iv. To provide the students with basic knowledge of electrochemistry, electrochemical cell and their thermodynamic account.
Syllabus:

Learning Outcomes:
Cognitive (Knowledge, Understanding, Application, Analysis, Evaluation, Synthesis)
i. To collect and interpret the thermodynamic properties and their change in a physical chemical process.
ii. To analyse the state, the direction and the limit (equilibrium) of change of a physical chemical process using generalised thermodynamic laws and functions.
iii. To perform quantitative calculation on systems, such as the phase transformation of a pure substance, the mixing and phase transformation of two components, using functions derived from thermodynamics with the properties associated with specific systems.
iv. To apply graphic technique in analysing the presence and the stability of multiphase in a multi-component (limited to three) system.
v. To examine key system properties associated with an equilibrium state by means of commonly used experimental techniques.
vi. To describe the conversions between electric and chemical energies in an electrochemical cell based on the configuration of the cell and the electrochemical reactions that take place in it.

vii. To demonstrate proficiency in experimentally determining the properties of phase transition and of electrochemical cell
viii. To set up an electrochemical cell and perform measurement of key electrical properties of the cell.
How the Module will be Taught and what will be the Learning Experiences of the Students:
This module will be taught over 12 weeks within one semester. There will be 3 hours interactive lectures each week and the tutorial will be incorporated into these lectures. A series of laboratory practicals (6 x 3 hours sessions spaced during the semester) relevant to the lecture materials will be included as a part of the module delivery. Students will be requested to complete each of these experiments and present by each student an written laboratory report containing a description of the theory, methods and procedure of experiment, the processing/calculation of data collected, and the extraction/determination of certain kinetic parameters. The laboratory report from each of practicals forms a part of the assessment for each student.
The module will be assessed by means of an written examination (65%) at the end of a semester, plus all 7 laboratory reports (25%), and an oral viva (10%) on both laboratory and course works.
