Passing steam over hot carbon produces a mixture of carbon monoxide and hydrogen: H20(g) + C(s) -> CO(g) +H2(g) Write equations for the equilibrium partial pressures of H2O, CO, and H2. PH2O = 0.442 atm and PCO = 5.000 atm at the start of the reaction. The carbon is in excess. Let the variable x represent the change in partial pressures.

ynthesis gas, a mixture that includes the fuels carbon monoxide and molecular hydrogen, is used produce liquid hydrocarbons and methanol. It is made at pressures up to 100 atm by oxidation of methane followed by the steam re-forming and water-gas shift reactions. Because the is exothermic, temperatures reach 950 1100°C, and the conditions are such that the amounts of hydrogen, carbon monoxide, carbon dioxide, methane and water leaving the reactor are close to the equilibrium amounts for the steam re-forming...
