Hint: Let us first know about rust. Rust is an iron oxide, a typically reddish-brown oxide generated when iron and oxygen react catalytically in the presence of water or air moisture. Rust is made up of hydrous iron oxides and iron oxide-hydroxide ( and it is commonly connected with refined iron corrosion.
Complete answer:
Let us get some idea about endothermic and exothermic reactions. Exothermic reactions release energy into the environment, raising the temperature of the environment. Endothermic reactions absorb energy, lowering the temperature of the environment.
The process of rusting is an exothermic reaction. It's because the rust-producing process between iron and damp air releases a lot of heat. However, the reaction normally takes place at such a sluggish rate that the release of heat is barely apparent. To put it another way, rust is caused by the gradual oxidation of iron (Fe) by oxygen. Iron oxide is often created when new bonds are created and heat is released during the whole process.
Note:
The prevention or delaying of rust is the basis of substantial economic operations in a variety of specialised technologies due to the widespread usage and importance of iron and steel products. Here's a quick rundown of the methods; read the cross-referenced articles for further information. Because rust is permeable to air and water, the internal metallic iron behind the rust coat corrodes. Rust prevention hence necessitates the use of anti-rust coatings.
