Table shows the results of the data fitting of the Gibbs energy of formation of the loaded sorbent MgCl2⋅NH3 at different temperatures. At the reference temperature of 298 K, the Gibbs energy of formation is additionally calculated using a group contribution method presented by Mostafa and Eakman. Since the deviation of the fitted value to the one obtained by the group contribution method is well below 1 %, the fitting procedure can be assumed to yield reliable results.
