Example

# Problem: One reaction that occurs in producing steel from iron ore is the reduction of iron(II) oxide by carbon monoxide to give iron metal and carbon dioxide. The equilibrium constant, K p, for the reaction at 1000 K is 0.259. FeO (s) + CO (g) ⇌ Fe (s) + CO 2 (g)                 K p = 0.259 at 1000 K. What is the equilibrium partial pressure of CO at 1000 K if the initial partial pressures are P CO = 1.000 atm and P CO2 = 0.500 atm? A) 1.191                B) 0.121          C) 0.241          D) 0.359          E) 0.191
