If you heat up co2 to billions of degrees what happens

Question

I have been wondering for my project for science and no I'm not cheating your supposed to look it up or ask somone what would happen but what does happen when you heat up co2 to billions of degrees like if you put it inside a star made of flaming plutonium, helium, quark gluen plasma, hydrogen, hot nitrogin, carbon monoxide and crud like that basicly my science thing I'm doing is taking a question I always have and answering it becouse I know that a black hole came from a callapsed core of a star you know and the atoms themselves collapse wich is called a singularity I'm wondering if you uncollapsed the atoms and decrease the gravity I know it would more likely be like a neutron star but I'm saying if it already sucked in a lot of stuff basicly I'm trying to find out if you mix every element on the periodic table and have the thing have a lot of mass and is really dense not as dense as a black hole but dence where the star or the thing heats up a lot so yeah can you please help me with this one question if you heat up co2 what happens becouse I pretty much got a lot of stuff except this one question

Answer 1

2CO2 ->2CO + O2 is a reversible reaction.

         <-

 

The following TABLE by Trevor & Kortwright gives calculated values of the decomposition of CO2 at various temperatures and pressures. It shows that at 3500C & 1 Atm. pressure, 46% of CO2 decomposes into CO and O2. Beyond 3500C, no further changes occur, i.e., a maximum occurs at 3500C.

 

Trevor and Kortwright have calculated the percentages of dissociation of carbon dioxide at different temperatures and pressures to be as follow, the heat of dissociation Qt, also being derived from the temperature:

 

Temp.°C.   0.001   Atm 0.01   Atm 0.1   Atm 1   Atm 10   Atm 100 Atm   Qt
