Learning Outcomes of the Course Unit |
---|
- 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 |
