    Question
    SLPaper 1A

    Consider the following reactions:

    Fe2O3(s)+CO(g)→2FeO(s)+CO2(g)ΔH⊖=−3 kJFe_2O_3 (s) + CO (g) → 2FeO (s) + CO_2 (g) \quad \Delta H^\ominus= −3 \, kJFe2​O3​(s)+CO(g)→2FeO(s)+CO2​(g)ΔH⊖=−3kJ

    Fe(s)+CO2(g)→FeO(s)+CO(g)ΔH⊖=+11 kJFe (s) + CO_2 (g) → FeO (s) + CO (g) \quad \Delta H^\ominus = +11 \, kJFe(s)+CO2​(g)→FeO(s)+CO(g)ΔH⊖=+11kJ

    What is the ΔH⊖\Delta H^\ominusΔH⊖ value, in kJ, for the following reaction?

    Fe2O3(s)+3CO(g)→2Fe(s)+3CO2(g)Fe_2O_3 (s) + 3CO (g) → 2Fe (s) + 3CO_2 (g)Fe2​O3​(s)+3CO(g)→2Fe(s)+3CO2​(g)
