Thermodynamics of the anions/CO2 reactions in
the gas phase
The approach adopted to quantify the energies for each reaction is
represented in equation 8, where the anion (A-) reacts
with CO2 to form the adduct
[A-CO2]-.
\(X=\ \left(X_{\left[{A-\text{CO}}_{2}\right]-}\right)-\ \left(X_{A-}+\ X_{\text{CO}_{2}}\ \right)\)
with X being the enthalpy (H) or Gibbs free energy (G).
