Question
Which is NOT an example of a redox reaction?*RustingCollisionThermite ReactionCellular Respiration
Solution
The option that is NOT an example of a redox reaction is "Collision".
Redox reactions, or reduction-oxidation reactions, involve the transfer of electrons from one molecule to another.
-
Rusting is a redox reaction where iron reacts with water and oxygen to form hydrated iron(III) oxide, commonly known as rust. In this process, iron is oxidized and oxygen is reduced.
-
The thermite reaction is a famous redox reaction where aluminum reduces iron(III) oxide to produce iron and aluminum oxide. Here, aluminum is oxidized and iron(III) oxide is reduced.
-
Cellular respiration is a series of redox reactions that occur in cells to produce energy. Glucose is oxidized to produce carbon dioxide and water, and in the process, oxygen is reduced.
-
A collision, on the other hand, is a physical process, not a chemical one. It does not involve the transfer of electrons and hence, is not a redox reaction.
