Subject aims expressed by acquired skills and competences
- to define the thermodynamic quantities and laws of thermodynamics
- 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 equilibria of pure
substances and binary liquid systems
- to define and utilize basic terms of chemical kinetics - rate of chemical reaction,
kinetic equation, order of reaction, rate constant
- to describe basic processes of heterogeneous reactions – diffusion, adsorption;
to determine the rate-limiting process for heterogeneous processes
- to apply gained theoretical knowledge in the field of material preparation in
electrical engineering.
