[𝐶𝑂 2 (𝑎𝑞)] = 𝐶 𝐻𝑒𝑛𝑟𝑦 𝑝𝐶𝑂 2 where 𝐶 𝐻𝑒𝑛𝑟𝑦 is the Henry's constant, assumed to be 35 mM/bar at room temperature. Given that the present thermodynamic analysis serves as an overview of the interplay between the nucleophilicity-swing and pH-swing mechanisms, we focus on the above main reactions while those leading to intermediate compounds such as AQ(CO2) 2-and AQHCO2 -and species formed due to mixed mechanisms are assumed to be disregarded for lack of estimation for them and for simplicity.
