Two reaction progress variables are needed. These are chosen as:

Other choices of reaction progress variables are possible, but the calculated equilibrium composition would be unaffected. Assuming that the initial gas is pure water vapor, the setup is shown in Table 9.2. From the definitions above and the balancing numbers in the equilibrium reactions, the moles of OH produced are twice those of H2 produced. Substituting the equilibrium mole fractions from the table into Eqs (9.29) yields:
