Final answer:
The given reaction represents the corrosion of iron (Fe) with oxygen (O2) to form iron oxide (Fe2O3) and release energy. The reaction is exothermic and involves the exchange of electrons between elements.
Step-by-step explanation:
In the given question, it is mentioned that the reaction is:
2Fe2O3 ⟶ 4Fe + 3O2 δ∘rxn= 824.2 kJ
This reaction represents the corrosion of iron (Fe) through the reaction with oxygen (O2) to form iron oxide (Fe2O3). The reaction is exothermic, releasing 824.2 kJ of energy. The balanced equation shows that 2 moles of Fe2O3 react to form 4 moles of Fe and release 3 moles of O2 gas.
The reaction demonstrates an important concept in chemistry, which is the exchange of electrons between elements. Iron loses electrons (oxidation) to form Fe2O3, while oxygen gains electrons (reduction) to form O2.
