The reduction of iron(III) oxide to iron during steel-making can be summarized by this sequence of reactions: +2CsO2g ⇌ 2COg K1 +Fe2O3s3COg ⇌ +2Fel3CO2g K2 The net reaction is: +2Fe2O3s+6Cs3O2g ⇌ +4Fel6CO2g K Write an equation that gives the overall equilibrium constant K in terms of the equilibrium constants K1 and K2. If you need to include any physical constants, be sure you use their standard symbols, which you'll find in the ALEKS Calculator.
