6. For the reaction H2O(g) + CO(g) H2(g) + CO2(g) at 700C, the equilibrium constant Kc is 1.87. If 0.03 moles of H2O and 0.03 moles of CO are heated to 700C in a 1 litre container, what is the equilibrium concentration of H2 (in units of mol L-1)? 7. What is the equilibrium constant for the reaction CO3-(aq) + 2H+(aq) H2CO3(aq) given the equilibrium constants for H2CO3(aq) HCO3(aq) + H+(aq) K = 4.2 10-7 HCO3(aq) CO32(aq) + H+(aq) K = 4.8 10-11 Note: by adding reaction equations, you multiply equilibrium constants.
