The aim of this work is to discuss the use of quite different modified forms of Saha and Guldberg-Waage equations to determine the composition of CxHyOzNt plasmas in a nonequilibrium thermal state. x, y, z, and t are the initial proportions of carbonic, hydrogen, oxygen, and nitrogen atoms. The computation is made under condition of pressure and electron temperature in the range, respectively, 0.1-1 MPa and 5-30 103 K. We show the influence of each form of Saha and Guldberg-Waage equations on the evolution of major species density, such as hydrogen components (H, H2), carbon monoxide (CO), and electrons. These species have a significant influence on the plasma's performances such as thermal and electrical conductivity through the equilibrium composition. We also give the influence of internal partition function calculation on species concentration within the plasma and discuss the choice of internal temperatures.
