Learning outcomes |
The aim of the object is to allow students more familiar with the use of published equilibrium data for computations of composition of equilibrium systems, mutual influences of chemical equilibria, as well as for calculations of conditional quantities and their practical use in computations of complex systems.
Student passing through the object is able to describe and solve complex computations of equilibrium systems. |
Prerequisites |
Student has to participate the lectures combined with practical training of computations.
|
