3.0 moles each of carbon monoxide, hydrogen, and carbon are placed in a 2.0 liter vessel and allowed to come to equilibrium according to the equation: CO(g)+H2(g)-->C(s)+H20(g)
if the equilibrium constant at the temperature of the experiment is 4.0, what is the equilibrium concentration of water vapor?

    3.0 mols/2.0 L = 1.5M
    ..........CO + H2 ==> C + H2O
    initial..1.5..1.5....1.5...0
    change....-x...-x.....x....x
    equil...1.5-x..1.5-x..x....x

    Kc = 4.0 = (H2O)/(C0)(H2O)
    Substitute from the ICE chart into the Kc expression and solve for x.

    [H2O]=.81

  3. Jenny

    [H2O]=1M

  4. Mohin

    H2O = 9M
