THERMODYNAMIC CALCULATION SOFTWARE AND ITS APPLICATION

The development, functions and application of a thermodynamic calculation software are introduced in this paper. The reaction equations can be balanced automatically by analysising the elements in the reaction components, and the thermodynamic functions such as Gibbs free energy, enthalpy and equilibrium constant can be calculated by using the expandable inorganic thermodynamic database. The calculation results can be presented in the format for the input of graph mode software. The user can easily obtain the relationships between temperature and change of Gibbs free energy, partial pressure (or ratio of partial pressure) of gas phase for actual reactions, with only requirements of activities of reaction components.
