${\text{Fe}}_{\text{2}}{\text{O}}_3+2\text{A}l\to \text{A}{l}_2{\text{O}}_3+2\text{Fe}$

The above reaction is an example of

The given chemical equation is

${\text{Fe}}_{\text{2}}{\text{O}}_3+2\text{A}l\left(s\right)\to \text{A}{l}_2{\text{O}}_3+2\text{Fe}\left(s\right)$

It is a chemical displacement reaction because ‘Al’ is more reactive than Fe. Therefore, Al is displaces Fe from ${\text{Fe}}_{\text{2}}{\text{O}}_3$.
