You are here
Fe 2 O 3 + 2Al → Al 2 O 3 + 2Fe
The above reaction is an example of a
(a) combination reaction.
(b) double displacement reaction.
(c) decomposition reaction.
(d) displacement reaction.
Answer
(d) displacement reaction
Explanation
Reaction in which a more reactive element takes the place of a less reactive element in a chemical compound is called Displacement Reaction.
Fe 2 O 3 + 2Al → Al 2 O 3 + 2Fe
In the above reaction,
Al displaces Fe from it’s compound Fe 2 O 3 and forms Al 2 O 3 .
(Since Al is more reactive than Fe, and is above Fe in the reactivity series)
