Annotation -
A review of approaches for solving of basic chemical and ionic equilibrium is carried out. An extension for simultaneous reactions is then explained. Non-stoichiometric forms of equilibrium conditions and method of solving chemical equilibrium in systems with high number of reactions is discussed. Thermodynamic properties of the system containing solid solutions and alloys are demonstrated as well.

Aim of the course -

Students will be able to:

  • calculate the chemical equilibrium for simple reactions,
  • solve chemical or ionic equilibrium for small number of simultaneous reactions,
  • understand of approaches for solving chemical equilibrium in systems with high number of reactions
  • solve chemical equilibrium in systems containing solid phase
