Subject aims expressed by acquired skills and competences
- to define thermodynamic quantities and thermodynamic laws
- to utilize the fundamental thermodynamic quantities (enthalpy, entropy, Gibbs
energy) for the system behaviour describing
- to describe the chemical equilibrium – to monitor the dependence of the
equilibrium constant on state variables (dependence on temperature, dependence
on pressure)
- to describe the phase equilibrium, Gibbs phase rule, phase equilibrium of pure
substances
- to define and to utilize basic terms of chemical kinetics - homogeneous and
heterogeneous reaction, rate of chemical reaction, kinetic equation, order of
reaction, rate constant
- to monitor the dependence of the reaction rate on temperature and on pressure
- to describe basic processes of heterogeneous reactions – diffusion, adsorption;
to determine the rate-limiting process for heterogeneous processes
- to apply gained theoretical knowledge in routine
