H2(g) + CO2(g) H2O(g) + CO(g)
At a certain temperature, an equilibrium mixture in a 10.0 L container was analyzed and found to contain 2.00 moles of H2, 2.00 moles of CO2, 1.00 mole of H2O, and 2.00 moles of CO. How many moles of water vapor would have to be added to the container to increase the concentration of H2 to 0.320 M when equilibrium is re-established?
