Fe2O3 + 2Al → Al2O3 + 2Fe The Reaction is an Example of a(A) Combination reaction.(B) Double Displacement reaction (C) Decomposition reaction (D) Displacement reaction

Answer: D. Displacement Reaction

The activity series is a table that lists metals in decreasing order of relative reactivity according to which displacement reaction occurs. The metals at the top are more reactive displacing those at the bottom having a less reactive nature.

A displacement reaction is one in which one reactant is partially replaced by another reactant.

Fe₂O₃ + 2Al → Al₂O₃  + 2Fe is a displacement reaction because:

• Aluminum (Al) has higher reactivity than Iron (Fe).
• As aluminum is more reactive than iron, it displaces iron and forms aluminum oxide. 
• Here only a single displacement takes place between aluminum and iron.
