First you need to work on the Kp expression. SOLIDS aren't used (pure liquids aren't either) so the expression is 1/pCO2 = Kp. The problem tells you that AT EQUILIBRIUM [CO2] = 0.150M. I would calculate Kc from Kc = 1/([CO2] then convert to Kp by Kp = Kc(RT)Dn

I'm not exactly sure of what you want but I can give you a start, perhaps. This is a redox reaction. The beginning concns are too high on the right; therefore, the reaction must shift to the left to reach equilibrium. [You can show this by Qp = 0.115/0.215 = 0.534 and this...
