CHY1201 : Elements of Physical Chemistry

Semester 2 Credit Value: 20
ECTS Credits: 10.0


To provide an essential understanding of basic thermodynamic principles, chemical kinetics and spectroscopy and, in conjunction with the stage 1 physical chemistry laboratory class, an introduction to some experimental techniques which can be employed in physical chemistry

Teaching Rationale And Relationship

Knowledge and understanding are acquired through lectures. The calculation classes will increase the ability of students to solve quantitative problems and carry out calculations in physical chemistry. Practicals are designed to reinforce the taught material and practice written, experimental, computer and problem solving skills. The drop in sessions allow discussion between module staff and students.

Assessment Methods

The format of resits will be determined by the Board of Examiners
