IGE Model: An Extension of the Ideal Gas Model to Include Chemical Composition as Part of the Equilibrium State
Figure 3
The mole fractions of O2 molecules and O atoms in a one mole initial sample of oxygen gas at standard pressure. As temperature increases, O2 molecules dissociate into O atoms. At 6000 K, a one mole initial sample of oxygen gas will contain 2 moles of O atoms.
