Chemical-Reaction Equilibria: Molar Ratio Calculations

Please see the attached file for the fully formatted problem(s). Hydrogen gas is produced by the reaction of steam with "water gas," an equimolar mixture of H2 and CO obtained by the reaction of steam with coal. A stream of "water gas" mixed with steam is passed over a catalyst to convert CO to CO2 by the reaction: H2O(g) +
