Module summary
This module will enhance students’ knowledge and understanding of the major areas of physical chemistry for the life sciences and further develop their ability to model physicochemical processes mathematically in order to be able to predict the behaviour of chemical systems. The module will examine key theories and applications of thermodynamics, the kinetics of life processes, quantum theory, heterogeneous catalysis and molecular spectroscopy.

Syllabus
Thermodynamics:
Revision of statistical thermodynamics; the measurement of entropies (the molecular interpretation of the Second and Third Laws, Boltzmann relation linking entropy and disorder, residual entropy and entropy changes accompanying spontaneous chemical reactions); Gibbs free energy criteria for irreversible processes; chemical potential; derivation of the Clapeyron and ClausiusClapeyron equations and the application of these equations to chemical equilibrium both qualitatively and quantitatively; enthalpy changes at the triple point using isotherms. LO1
Chemical kinetics of complex biochemical processes:
Revision of rates of reactions, rate laws, the steady state approximation and its application to mechanisms (elementary reactions, consecutive reactions). The MichaelisMenten mechanism of enzyme catalysis, the analysis of complex mechanisms and the catalytic efficiency of enzymes. Enzyme inhibition mechanisms (competitive, noncompetitive and uncompetitive), inhibitor efficiency, LineweaverBurke analysis. LO3,LO4
Microscopic systems and quantization:
The principles of quantum theory (atomic and molecular spectra, waveparticle duality, the uncertainty principle, the Schrödinger equation), application of quantum theory (particle motion in one dimension box and on a ring), hydrogenic atoms (permitted energy levels, radial distribution functions, spherical harmonics, atomic orbitals). Introduction to the application of quantum theory in computational chemistry. LO5
Heterogeneous catalysis and macromolecules:
Revision of adsorption processes and isotherms; derivation of fractional surface coverage expressions for competitive and dissociative molecular adsorption; LangmuirHinshelwood and EleyRideal mechanisms of bimolecular surface reactions; variation in unimolecular decomposition reaction rates with pressure. Properties and applications of natural and synthetic macromolecules and aggregates. LO2,LO3
Spectroscopy and Photochemistry:
General features of electronic, vibrational and rotational spectroscopy; selection rules; spectral broadening effects; anharmonicity; Rayleigh and Raman scattering; photochemical reactions (the Jablonski diagram, kinetics of excited state decay, fluorescence quenching, resonance energy transfer). LO3,LO6
Balance of independent study and scheduled teaching activity
Acquisition of knowledge of the subject matter of this module will be promoted through lecturerled lectures (22 hours) and tutorials (11 hours); directed webbased learning and through the guided use of studentcentred learning resources. Selfmanaged time and private study should be spread out over the whole semester. Additional exam preparation will be facilitated through a revision session (3 h). There will also be weekly dropin sessions, of one hour duration, which students can make use of in order to consolidate their understanding of the subject matter.
Learning outcomes
On successful completion of this module students will be able to:
1. Make a critical evaluation of entropy changes accompanying chemical reactions using thermodynamic methods
2. Evaluate the structural differences of selected macromolecules and relate this to their functions
3. Analyse the mechanism of a heterogeneous, photochemical or enzymatic reaction, use this to produce a sequence of elementary steps and provide a mathematical model for the rate of reaction
4. Critically assess and compare complex biochemical inhibition processes
5. Derive energy levels (eigenvalues) for a given system using quantum theory
6. Predict and interpret spectroscopic measurements and photochemical processes from the quantisation of energy levels
Assessment strategy
The module will be summatively assessed by means of a coursework component comprising several interpretation exercises (1500 words) and a one hour unseen written exam. The students must pass with an overall mark of 40%.
