Question

What is a thermite reaction? Explain with the help of an equation. State any one use of this reaction.

Answer 1

Thermit reaction is a highly exothermic single displacement reaction in which a high reactive metal displace the low reactive metal, the heat which is produce is so large that the metals are formed in molten state.

Example :-

$Fe_2O_3+Al=Fe+Al_2O_3+Heat$

• This reaction of iron oxide with aluminium is used to join railway tracks or cracked parts of machine

Answer 2

Termite Reaction :-

It is a highly Exothermic Reaction (i.e., It produces a lot of heat).The high reactive metal displace metal of low reactivity.

Termite Reaction is given below :-

Fe2O3 + 2Al ---------------> Al2O3 + 2Fe

(Iron Sulphate) + (Aluminum) -------------> (Aluminum Sulphate) + (Iron)
