Enthalpy reaction equation question

(1/1)

erucibon:
The question asks to write the chemical equation associated with the enthaply of formation of gaseous carbon dioxide with the equations:
1) SrO + CO2 -> SrCO3
2) 2SrO -> 2Sr + O2
3) 2SrCO3 -> 2Sr + 2C + 3O2
I'm not sure what the equation is supposed to be.
Thanks

Hey there!

Sorry it's been so long before you've received a reply - I somehow also managed to miss your question.

As I am not quite sure of the enthalpy values for each of the reactants/products, I'm not much help with the enthalpy side of the equation, however I have attached below an image of the final equation as I would calculate it.

Hopefully this can (maybe) still be helpful!
