CO is flammable, but CO2 unstable above 800 C ?


The Bouduouard equilibrium as described in worlds largest online chemistry textbook tells that above 700...800 C the equilibrium

CO2 + C <=> 2 CO

shift to the right, which would preclude combustion of CO in air (or oxygen), because the combustion temperature is well above 800 C.

So what makes CO still flammable ?

How would that preclude combustion? Carbon monoxide will still prefer to react with oxygen to give CO2 than to react with itself to give carbon dioxide and carbon. And any carbon that's produced by that reaction can still burn.

Combustion in air would be a different reaction:

2CO2 <=> 2CO + O2
