Description including Unit Aims

This unit develops the introduction to physical chemistry given in CHEM10003, CHEM10005 to provide the essential base of physical chemistry required for advanced study at Levels 6 and 7 (Years 3 and 4). It covers the main areas of the subject e.g. molecular energy, thermodynamics, chemical energy, equilibria, states of matter, properties of solutions (including electrolytes) and interfaces. Workshops are integral to the unit.

Intended Learning Outcomes

  • Understanding of the simple harmonic oscillator and vibrational modes;
  • Knowledge that confinement leads to quantisation of energy;
  • Understanding of the quantum mechanics of simple atoms and molecules;
  • An understanding of partition functions and density of states;
  • Ability to calculate internal energy and entropy from the partition function;
  • Apply the first and second law of thermodynamics to practical problems;
  • An understanding of Gibbs and Helmholtz energies;
  • Be able to predict a stable phase as a function of temperature;
  • Have an appreciation of the factors that influence equilibria in complex reactions;
  • An appreciation of photochemistry as a way of breaking bonds;
  • Be able to explain how rate equations relate to collision theory and elementary steps;
  • Understand vapour pressures for ideal and real mixtures;
  • Appreciate the stress dynamic nature of a surface;
  • Be able to explain fundamental properties of a curved surface;
  • Be able to apply the Nernst equation to unseen situations;
  • An appreciation of the reactions underpinning electrochemical energy conversion devices such as batteries, fuel cells and supercapacitors;
  • Understand the physical origins of intermolecular forces and molecular interactions;
  • Understand methods to model the structure and dynamics of liquids and protein.

Teaching Information

Teaching will be delivered through a blended combination of synchronous and asynchronous sessions. Synchronous sessions include lecture style and interactive delivery and workshops. Workshops will in particular provide opportunity for live interaction with groups of students, feedback on exercises set as independent study and preparation for forthcoming material. There will be associated asynchronous activity involving independent study, problem solving and self-directed exercises. Synchronous revision sessions as well as drop-in clinics will be offered.

Assessment Information

End-of-TB1 timed, open-book examination (50%) End-of-TB2 timed, open-book examination (50%)


If this unit has a Resource List, you will normally find a link to it in the Blackboard area for the unit. Sometimes there will be a separate link for each weekly topic.

If you are unable to access a list through Blackboard, you can also find it via the Resource Lists homepage. Search for the list by the unit name or code (e.g. CHEM20190).

How much time the unit requires
Each credit equates to 10 hours of total student input. For example a 20 credit unit will take you 200 hours of study to complete. Your total learning time is made up of contact time, directed learning tasks, independent learning and assessment activity.

See the Faculty workload statement relating to this unit for more information.

The Board of Examiners will consider all cases where students have failed or not completed the assessments required for credit. The Board considers each student's outcomes across all the units which contribute to each year's programme of study. If you have self-certificated your absence from an assessment, you will normally be required to complete it the next time it runs (this is usually in the next assessment period).
The Board of Examiners will take into account any extenuating circumstances and operates within the Regulations and Code of Practice for Taught Programmes.
