The article "Simulation of the Hot Carbonate Process for Removal of CO, and H,S from Medium Btu Gas" (K. Park and T. Edgar, Energy Progress, 1984:174–180) presents an equation used to estimate the equilibrium vapor pressure of CO, in a potassium carbonate solution.

Question
The article "Simulation of the Hot Carbonate Process for Removal of CO, and H,S from
Medium Btu Gas" (K. Park and T. Edgar, Energy Progress, 1984:174–180) presents an
equation used to estimate the equilibrium vapor pressure of CO, in a potassium carbonate
solution. The actual equilibrium pressure (in kPa) was measured in nine different reactions
and compared with the value estimated from the equation. The results are presented in the
following table:
