Question

6 The following data are needed for this question.
(CO(g)) = –111 kJ mol–1 (CO2(g)) = –394 kJ mol–1 (Fe2O3(s)) = –822 kJ mol–1
Carbon monoxide reacts with iron(III) oxide.
3CO(g) + Fe2O3(s) → 3CO2(g) + 2Fe(s)
What is the enthalpy change when 55.8 g of iron are produced by this reaction? A –27.0kJ B –13.5kJ C +13.5kJ D +27.0kJ
