Application of the Element Potential Method to Gaseous Chemical Equilibrium Calculation

The equilibrium state of a mixture of chemically reacting perfect gases at fixed enthalpy and pressure is formulated in terms of the Massieu element potentials by the application of the entropy maximization principle. An iterative solution technique is presented to obtain the parameters appropriate to the equilibrium state. A method for obtaining starting values and a stability criterion based upon the element potential method are presented. A perturbation technique is developed to predict the equilibrium state for different enthalpy, pressure, and atomic mole number constraints, given the solution for one set of constraints
