Prior learning requirements
CH4005 and CH5010 or equivalent
The aims of this module are aligned with the qualification descriptors within the Quality Assurance Agency’s, Framework for Higher Education Qualifications.
The module aims to: extend students’ knowledge of aspects of thermodynamics, Chemical kinetics and Microscopic systems; introduce students how physical chemistry gives quantitative insight into biology and biochemistry and the consequences of a quantum theoretical approach to describing the structures of many- electrons atoms; provide an underpinning theoretical basis for optical (atomic and molecular) spectroscopy; and assist students to develop the application of physical chemistry to a specific biological or biomedical problem, such as pharmacokinetics.
This module aims to provide students with the qualities and transferable skills necessary for employment requiring: the exercise of initiative and personal responsibility; decision-making in complex and unpredictable contexts; and, the learning ability needed to undertake appropriate further training of a professional or equivalent nature.
Thermodynamics: Introduction to statistical thermodynamics; The measurement of entropies (The molecular interpretation of the Second and Third laws, Boltzmann relation linking entropy and disorder, residual entropy and exceptions to the third law, Entropy changes accompanying chemical reactions); Gibbs free energy criteria for irreversible processes; Chemical potential, derivation of the Clausius-Clapeyron and Clapeyron equations, application of these equations to chemical equilibrium both qualitatively and quantitatively; Thermodynamics of ion and electron transport (Transport of ions across biological membranes, Applications of standard potentials)
Molecular interactions and Materials: macromolecules and aggregates, Metallic, ionic, and covalent solids and Solid surfaces
Chemical kinetics: The rates of reactions and accounting for the rate laws, The steady state approximation and its application to mechanisms (Elementary reaction, Consecutive reaction, experimental evidence for the existence of free radicals). Diffusion control, Kinetic and thermodynamic control.
Complex biochemical processes: Enzymes (Michaelis-Menten mechanism of enzyme catalysis, the analysis of complex mechanisms, the catalytic efficiency of enzymes, enzyme inhibition), Electron transfer in biological systems (The rates of electron transfer processes).
Microscopic systems and quantization: The principles of quantum theory (Atomic and molecular spectra, Wave – particle duality, The Schrodinger equation), Application of quantum theory (Motion in one dimension, A particle on a ring), Hydrogenic atoms (the permitted energy levels of hydrogenic atoms, Atomic orbitals),
Spectroscopy: General features of spectroscopy, Photochemistry (The kinetics of decay of excited states, Fluorescence quenching, Fluorescence resonance energy transfer).
Learning and teaching
Teaching and learning is comprised of lectures, tutorials, on-line material and guided study with particular emphasis on solving problems in physical chemistry.
Lectures (30 h) are used to introduce the subject material and are linked to progress tests and an end of module examination.
Tutorials (15 h) are used to reinforce key concepts and to develop problem solving skills through advice, on an individual or group basis as appropriate, on a series of pre-set graded problems.
Students will be expected to review appropriate topics prior to tutorials (5 h) and to work on assigned problems (30 h) as an aid to developing an understanding of the course material.
Students are also expected to review material and develop their understanding of physical concepts independently (60 h).
The module is supported by a website on WebLearn which icludes a number of electronic learning aids. Students would be expected to use the site for assisted study (10 h).
On successful completion of this module, a student will be able to:
- Calculate the Gibbs energy for an enzyme-catalysed reaction and the solubility of a compound from a knowledge of the behaviour of ions in solution utilising an understanding of the principles ofthermodynamics,;
- Make a critical evaluation of entropy changes accompanying chemical reactions using biochemical thermodynamic methods;
- Evaluate the structural differences of selected macromolecules and relate this to their functions;
- Analyse the mechanism of a reaction, use this to produce a sequence of elementary steps and provide a mathematical model of the rate of reaction;
- Give an assessment of the significance of selected complex biochemical processes;
- Derive the energy levels for a given system using quantum theory;
- Predict and interpret spectroscopic measurements from the quantisation of energy levels.
The module will be assessed by means of an end of module examination (50%, 1.0 hour) which will assess the students’ abilities to think critically, solve problems and communicate the implications of results effectively and by a coursework component (50%, 1500 words). The coursework component will consist of an assigned problem, which will also develop problem solving and communication skills.
A minimum aggregate mark of 40% will be required to pass the module. If the module is passed on reassessment, then the maximum mark awarded will be 40%.
