On Calculation of Heat Capacities of Chemically Reacting Gases

Applying the law of masses involved, algebraic formulae are derived for calculation of heat capacities of chemically reacting gas mixture. It is shown that the reaction part of heat capacities can be presented in a form of quadratic polynomial relative to thermal effects of reactions (occurring in gas) that has coefficients depending on stoichiometric factors of reactions and equilibrium values of mole fractions of the mixture components. The obtained formulae may be used in calculation of heat capacities of chemically reacting gas mixtures.
