Boudouard reaction
The Boudouard reaction, named after Octave Leopold Boudouard, is the redox reaction of a chemical equilibrium mixture of carbon monoxide and carbon dioxide at a given temperature. It is the disproportionation of carbon monoxide into carbon dioxide and graphite or its reverse: 2CO ⇌ CO2 + C The Boudouard reaction to form carbon dioxide and carbon is exothermic at all temperatures.
