Gasification of char (primarily carbon) with steam following coal pyrolysis yields a gas mixture of 1 kmol

Question:

Gasification of char (primarily carbon) with steam following coal pyrolysis yields a gas mixture of 1 kmol CO and 1 kmol H2. We wish to upgrade the hydrogen content of this syngas fuel mixture, so it is fed to an appropriate catalytic reactor along with 1 kmol of H2O. Exiting the reactor is a chemical equilibrium gas mixture of CO, H2, H2O, and CO2 at 600 K, 500 kPa. Determine the equilibrium composition. Note:
