At 1000 K, iron metal is produced through the reaction FeO(s) + CO(g) Fe(s) + CO_2(g) temperature, the equilibrium constant of the reaction is K_e = 0.259. An experiment, is from a mixture containing a solid phase consisting of 4 moles of FeO and 2 moles of Fe and consisting of 1.000 M CO and 0.500 M CO_2. The reaction was followed until the concentration reactants and products showed no further change with time. At this point, the concentration...
