\nThe statement that is NOT correct about the given reaction is that it is highly endothermic reaction.
\n<\/section>\n
\nThe reaction Fe2<\/sub>O3<\/sub>(s) + 2Al(s) \u2192 2Fe(s) + Al2<\/sub>O3<\/sub>(s) is known as the thermite reaction. It is a highly exothermic reaction, releasing a large amount of heat. Aluminum is more reactive than iron and displaces iron from its oxide, making it a displacement reaction. Fe2<\/sub>O3<\/sub> is reduced (loses oxygen), so it acts as an oxidizing agent. The large amount of heat produced makes this reaction useful for welding, including joining railway tracks.
\n<\/section>\n
\nThe thermite reaction releases so much heat that the iron produced is in a molten state, which is essential for its application in welding. An endothermic reaction absorbs heat from the surroundings, which is the opposite of what happens in the thermite process.
