Pre-requisites before taking this module (or general academic requirements):

CHEM260 Year 2 of MChem or BSc (Hons) Chemistry programme. UGT Students are expected to have completed CHEM260. PGT students should have completed a BSc (Hons) Chemistry programme with an equivalent level of Physical Chemistry to CHEM260. 


The aim of this module is to extend a student''s knowledge of Physical Chemistry, in particular to demonstrate the relationship between microscopic and macroscopic models for physical chemical phenomena, the quantum mechanical description of chemical bonding and the physical chemistry of electrochemical cells, surfactants and colloids.

Learning Outcomes

By the end of the module, students should:

  • understand how macroscopic physical properties of a system are related to microscopic properties of molecules;
  • understand bonding in molecules from quantum mechanical principles;
  • understand the role of electron density in describing the properties of chemical bonds;
  • have an understanding of the physical chemistry of ideal and real electrochemical cells;
  • have an understanding of the physical chemistry of surfactants and colloids;
  • be able to apply their knowledge of physical chemistry to solve unseen problems.
