Be sure to answer all parts. A key step in the extraction of iron from its ore is FeO(s) + CO(g) ⇌ Fe(s) + CO2(g) Kp = 0.403 at 1,000°C This step occurs in the 700°C to 1,200°C zone within a blast furnace. What are the equilibrium partial pressures of CO(g) and CO2(g) when 1.4300 atm of CO(g) and excess FeO(s) react in a sealed container at 1000°C?
