Question

Quizplus · Accepted Answer

The enthalpy of the reaction is -59.0 kJ. This can be calculated by adding the enthalpies of the two reactions given in the question:Fe₂O₃ (s)+ 3CO (s)→ 2Fe (s)+ 3CO₂ (g)ΔH = -28.0 kJ3Fe (s)+ 4CO₂(s)→ 4CO (g)+ Fe₃O₄(s)ΔH = +12.5 kJ3Fe₂O₃ (s)+ CO (g)→ CO₂ (g)+ 2Fe₃O₄ (s)ΔH = -28.0 kJ + 12.5 kJ = -59.0 kJ
