Temperature dependence of the rate of a chemical reaction - Arrhenius equation, possibilities of determination of activation energy, preexponential factor. 5. Theory of chemical kinetics - collision theory, theory of absolute reaction rates. 6. Kinetics of heterogeneous reactions, basic steps of heterogeneous reaction - diffusion, adsorption, chemical reaction on phase interface. 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 principles – external and internal diffusion. 7. Heterogeneous process with consecutive and concurrent 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.
