When a metal reacts with a compound of a different metal, the more reactive metal displaces the less reactive metal from its compound. The reaction is a redox reaction.
The thermite reaction is an exothermic reaction used for thermite welding in the railway industry to join rails together.2Al(s) + Fe2O3(s) → Al2O3(s) + 2Fe(s)This reaction takes place in the solid state. The molten iron formed is used to fill the gap and it solidifies to join the rails together.
