Subject syllabus:

1. Terminology in chemical kinetics – reaction rate, rate equation, order of reaction, rate constant, molecularity, reaction mechanism. Classification of chemical reactions – simple and simultaneous reactions, homogeneous and heterogeneous reactions. 2. Homogeneous reactions - integrated form of the kinetic equation (first-order reactions, second-order reactions, third-order reactions, nth-order reactions), methods to determine reaction orders. Kinetics of simultaneous reactions (reversible, parallel and consecutive reactions) – kinetic description, rate-determining process. 3. Temperature dependence of the rate of a chemical reaction - Arrhenius equation, , posibilities of determination of activation energy, preexponential factor. 4. Theory of chemical kinetics - collision theory, theory of absolute reaction rates. 5. Kinetics of heterogeneous reactions, basic steps of heterogeneous reaction - diffusion, adsorption, chemical reaction on phase interface. 6. Mechanism and mathematical description of diffusion – molecular, convection and turbulent diffusion. Fick’s first and second law of diffusion, diffusion flux. Diffusion (transport) limited reactions - basic priciples – external and internal diffusion. 7. Heterogeneous process with consecutive and concurent steps, diffusion and chemical resistance. Effect of various agents on diffusion kinetics. Diffusion limited heterogeneous process - technological examples. 8. Surface phenomena and kinetics of reactions. Physical adsorption and chemisorption. Surface properties of solid compounds, principles of adsorption processes. Electronic structure and adsorption properties of metals, adsorption on semi-conductors and insulators. Adsorption at the solid/gas interface and solid-liquid interface. 9. Empirical a theoretical adsorption isotherms - Freundlich's and Langmuir´s isotherms, BET model of adsorption isotherm. Temperature and pressure effect on adsorption and desorption processes. Application of surface processes – examples. 10. Kinetics of topochemical reactions, desription and analysis of particular periods. Kinetic curves. Nucleation of new phases. Influence of phase interface on kinetics. 11. Kinetics of heterogeneous reactions in first-order systems – melting, boiling, sublimation, freezing (crystallisation), condensation, polymorphic transformations. Examples of kinetics in second-order and higher-order systems. 12. Principles of catalysis, homogeneous and heterogeneous catalysis. Intermediate steps and kinetics of homogeneous catalytic reactions. Acid-basic catalysis. 13. Kinetics of heterogeneous catalytic reactions, mechanism, basic ideas of heterogeneous catalysis reactions. Catalysis by metals and non-metals. Kinetics and mechanism gaseous compounds by solid catalysator. Catalyst - selection, active centers, catalysts selectivity, promoters, poisoning and ageing of catalyst. Choice of catalyst – theory. Industrial application of heterogeneous catalysis. 14. Enzyme-catalytic reaction, Michaelis constant, enzyme inhibition.
