How much energy (in terms of heat) would have to be put into a molecule of CO2 to split it?

Question

Also, if you did split CO2 using heat, would the outcome be solid, liquid? When I say split I mean split it into carbon and oxygen.

Answer 1

To calculate the energy, you should have the heat of formation of CO2.

C(graphite) + O2(g STP) ===> CO2(g STP) DH = -? kJ

Then the energy needed to split it would be +? kJ. The products of splitting would be graphite and STP O2(g). If you wanted liquid oxygen and another allotrope of carbon, you'd have to add additional calculations to get there.

Answer 2

you always ask other people for the answers to homework instead of doing it urself?
