2CO + O₂ → 2CO₂
Explanation:
* Reactants:
* Carbon monoxide (CO) is the fuel, and it is being oxidized.
* Oxygen (O₂) is the oxidizer.
* Products:
* Carbon dioxide (CO₂) is formed as the product of the reaction.
Oxidation States:
* Carbon in CO: +2
* Carbon in CO₂: +4
* Oxygen in O₂: 0
* Oxygen in CO₂: -2
Mechanism:
The reaction involves the breaking of the triple bond in carbon monoxide and the double bond in oxygen. The carbon atom in CO gains two electrons from the oxygen atoms in O₂, increasing its oxidation state from +2 to +4. This process releases energy, which is why the reaction is exothermic.
Significance:
This reaction is essential for several reasons:
* Combustion: It is the primary reaction in the combustion of fuels like natural gas, propane, and gasoline.
* Environmental: It is the basis for the catalytic converter in cars, which converts harmful CO emissions into less harmful CO₂.
* Industrial: It is used in the industrial production of carbon dioxide, which is used in various applications.
