Throw some difficult Chemical Equilibrium questions at me.?
Need some difficult questions in preparation for an exam. Solubility equilibrium questions also accepted. Only exception is questions which revolve around pH.
I'm mainly after ones which take at least 10 minutes to complete and require some thinking. Please include the answer as well. Thanks.
Pressure equilibrium was not touched on and will not be assessed. I should've been more clear about that and included it in my original question.

Example 1: Given the standard Gibbs energy of reaction H2O(g) → H2(g) + 1/2O2(g) at 2000K is + 135.2 kJ mol-1, suppose that steam at 200k pa is passed through a furnace tube at that temperature. Calculate the mole fraction of O2 present in the output gas stream.
Answer and hint:
assuming the mole fraction of O2 equals x
PO2 = x* Ptotal,
PH2 = 2(x*Ptotal)
PH2O = Ptotal – PO2 – PH2 = (1-3x)Ptotal
