Steam reforming of methane (CH) produces "synthesis gas," a mixture of carbon monoxide gas and hydrogen gas, which is the starting point for many Important industrial chemical syntheses. An industrial chemist studying this reaction fills a 75.0 L tank with 38. mol of methane gas and 37. mol of water vapor at 42.0°C. She then raises the temperature, and when the mixture has come to equilibrium measures the amount of carbon monoxide gas to be 26. moll Calculate the concentration...

26. Synthesis of Hydrogen (Step 2) When the CO produced in the steam-methane reforming reaction is reacted with more steam at 450 K, the water-gas shift reaction: CO(g) + H20(g) CO(g) + H2(g) produces more hydrogen. If the equilibrium partial pressures of the gases in the reactor are 0.35 atm H2O 0.24 atm CO, 4.47 atm H2, and 4.36 atm CO2, what is the value of K?

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...
