Subject aims expressed by acquired skills and competences
- to define the thermodynamic quantities and thermodynamic laws
- to describe the chemical equilibrium – to monitor the dependence of the equilibrium
constant on state variables (dependence on temperature, dependence on pressure) –
to utilize Le Chatelier’s principle (effect of initial composition, pressure and inert
component on the equilibrium composition)
- to describe the phase equilibrium - Gibbs phase rule, phase equilibria of pure
substances and liquid-vapour equilibrium in mixtures
- to define and apply basic principles of chemical kinetics - rate of chemical reaction,
kinetic equation, order of reaction, rate constant, the theory of reaction rates
- to describe basic steps of heterogeneous process - physical processes limiting
kinetics of heterogeneous processes, diffusion, the Fick's first and second law,
adsorption, adsorption isotherms
- to apply the chemical thermodynamics a kinetics on the processes of combustion,
explosion and extinguishing

- účast na teoretickém cvičení menší než 79% ( více než 3 neúčasti)
poskytuje
možnost neudělení zápočtu
- úspěšné absolvování dvou samostatných výpočtových písemek – hodnocení
18+18 = max. 36 bodů
- oprava písemky – lze opravit maximálně jednu písemku maximálně jedenkrát.
Bodové hodnocení zápočtu:

Bodové hodnocení zkoušky: zkouška kombinovaná
- písemná část zkoušky - max. bodů 12
- ústní část zkoušky - max. bodů 50
V celkovém zisku bodového ohodnocení zkoušky musí být obsaženo jak nenulové
hodnocení výpočtové zkouškové písemky (min. 4 body za písemku) tak nenulové
hodnocení vlastní ústní zkoušky, tzn. student musí absolvovat obě části
zkoušky.
Bodové hodnocení předmětu se získá součtem bodů za cvičení a za absolvování
zkoušky. Výsledná klasifikace je dána podmínkami ve Studijním a zkušebním
řádu VŠB TUO.
