An efficient method is presented for calculating equilibrium chemical composition at a given pressure and stoichiometry with temperature, enthalpy, or entropy specified as the additional condition. A substantial reduction in computational time was achieved over conventional methods. Examples are given for the H2O2 system six equations reduced to two and CH2O2N2Ar system eleven equations reduced to three. A computer program is presented for solving problems with fuels which involve C and H hydrocarbon or hydrogen or N and H. Extension of the method to include other systems is explained in sufficient detail to eliminate the requirement for an extensive knowledge of chemistry by potential users.
