Solution: The definition of the  standard (molar) Gibbs energy of formation (ΔG f°) parallels that of ΔHf°; since ‘formation’ signifies a particular kind of reaction, what is the reaction corresponding to ΔGf° of CO2(g)? Given that ΔGf°(CO2(g)) = -394.4 kJ/mol, what can we say about the stability of carbon dioxide (relative to its elements)?
