8. If you add enough acid, you will convert all carbonate ions in solution to carbonic acid
(H₂CO3). Using the thermodynamic information below, calculate the standard Gibbs free
energy (kJ/mol) of this reaction:
C(s) + O2(g) → CO₂(g)
C(s) + O2(g) → CO3² (aq)
CO2(g) + H₂O(1)→ H₂CO3(aq)
AG 211.8 kJ/mol
AH-393.5 kJ/mol; AS°= 213.8 J/mol K
AH-677.1 kJ/mol; AS°= -56.9 J/mol K
AH -20.1 kJ/mol; AS°= -97.3 J/mol K
