<span>Answer:
CO2→CO + 12O2 is not a balanced reaction, I think you meant to post " CO2→CO + 1/2O2"
The simple answer is that the enthalphy for reaction 1 reversed is the same enthalpy as for the reaction as written but with the opposite sign.
If A + B = AB with 30 kJ released then
AB = A + B with 30 kJ absorbed.
We would write it as
A + B = AB heat of reaction = -30 kJ
AB = A + B heat of reaction = +30 kJ</span>
