Aims and Objectives
Having successfully completed this module you will be able to:
- calculate the equilibrium constants, standard Gibbs energy of reactions, and standard cell potentials for Galvanic cells
- explain and apply the concept of thermodynamic equilibrium.
- Set up glassware and apparatus to conduct experiments in Physical Chemistry.
- Evaluate the risks associated with an experiment and understand how to mitigate against those risks.
- Present the results of a practical investigation in a concise manner.
- explain aspects of titration curves and calculate the pH for different solution mixtures involving strong and weak acids and bases
- calculate the ionic strength and mean activity coefficient, account for the effect of ionic strength on equilibrium constant
- extract model parameters from experimental data sets.
- Interpret data from an experiment, including the construction of appropriate graphs and the evaluation of errors.
- define the terms and determine the enthalphy and entropy change associated with a reaction.
- explain the concept of spontaneity of a reaction and determine the Gibbs energy change associated with a reaction.
- differentiate elementary functions.
- explain the concept of a state function.
- comfortably handle a variety of mathematical expressions encountered in chemical sciences.
- solve linear and quadratic equations and systems of linear equations.
- Chemical thermodynamics: concepts of enthalphy, entropy and internal energy; first and second laws of thermodynamics; Hess cycles; use of energies of formation; definition and use of heat capacity; Gibbs energies and chemical potential; links to chemical equilbria; solution phase equilbria; activities and activity coefficients; effects of pressure and temperature on equilibrium constants; Le Chatelier’s principle; Henderson Hasselbach equation; exploration of equilibria, with emphasis on those important in aqueous acids and bases;
- Mathematical concepts in physical chemistry: Estimates and units; algebraic transformation rules; linear and quadratic equations; graphs and their analysis; exponentials and logarithms; linearization and data fitting; derivatives and differentiation; differentiation of simple functions and use of the chain, product, and quotient rules; use of derivatives to determine maximum and minimum points.
- Completion of two practical experiments and associated reports covering a range of topics and skills in physical chemistry including the measurement of materials and properties with accuracy, precision and reproducibility; and the estimation and treatment of errors; understanding the importance of experimental safety and time management.
Learning and Teaching
Teaching and learning methods

All absences from practical sessions must be validated and unexcused absences will result in failure of the module.
Repeat year externally: allowed if practical component passed. The practical marks are retained, the theory assessment is exam only.
Repeat year internally: note that practical may be reassessed by resubmission of reports or repeated.
This is how we’ll give you feedback as you are learning. It is not a formal test or exam.Tutorial
This is how we’ll formally assess what you have learned in this module.
This is how we’ll assess you if you don’t meet the criteria to pass this module.
