Understanding the Reaction
The reaction given is:
Fe2O3 + 2 Al → Al2O3 + 2 Fe
This is a significant chemical reaction known as a thermite reaction, which typically involves the reduction of metal oxides by aluminum.
What is a Displacement Reaction?
- A displacement reaction occurs when one element displaces another in a compound.
- In this case, aluminum (Al) displaces iron (Fe) from iron(III) oxide (Fe2O3).
Analysis of the Reaction
- Reactants: Iron(III) oxide (Fe2O3) and aluminum (Al).
- Products: Aluminum oxide (Al2O3) and iron (Fe).
Why is it a Displacement Reaction?
- Aluminum as a Reducing Agent: Aluminum is more reactive than iron, allowing it to replace iron in the compound.
- Change in Oxidation States: Iron in Fe2O3 is reduced (gains electrons), while aluminum is oxidized (loses electrons).
Types of Reactions Explained
- Combination Reaction: Two or more substances combine to form one product.
- Double Displacement Reaction: Exchange of ions between two compounds, typically in a solution.
- Decomposition Reaction: A single compound breaks down into two or more simpler substances.
Conclusion
Given that aluminum displaces iron from iron(III) oxide, this reaction is classified as a displacement reaction. Hence, the correct answer is option 'C'. This showcases the reactivity series of metals and highlights aluminum's ability to reduce metal oxides effectively.
