“…(17) Note that the CODATA tables (17) refer to CO 2 (aq) as "CO 2 (aq), undissoc". However, it is evident from the paper of Berg and Vanderzee (18) (on which the CODATA table entries for "CO 2 (aq), undissoc" are based) that "CO 2 (aq), undissoc" is the mixture of the species {CO 2 (aq) + H 2 CO 3 (aq)}. The importance of keeping this distinction clear has been emphasized by Alberty (19,20) who has also calculated standard molar formation properties for the aqueous species CO 2 and H 2 CO 3 , as well as standard molar transformed formation properties of aqueous carbon dioxide (the mixture of all carbon dioxide related species).…”

“…(17) We note that the values of the thermodynamic quantities for the ionizations of H 2 CO 3 and HCO − 3 used in this study (see table 3) are essentially the same as those that are calculated from the values of the standard molar thermodynamic properties given in table 7 in the paper by Berg and Vanderzee. (18) It is evident from the pK values given in table 3 that the species used in the reference reactions (5) and (6) are also the predominant species within the respective pseudoisomer (15) groups. Additionally, the pK values of all of the reactants, with the exception of H 2 CO 3 , are well removed (i.e.…”

“…Fortunately, the value of this pK is well known. (18) The equilibrium model used for the calculation of standard molar enthalpies r H o m for the reference reactions from the measured values of r H m (cal) has been described previously. (24) This model has been modified recently so that it now utilizes the Mathemat- ica (25) computer code of Alberty and Krambeck (26) to solve the simultaneous non-linear equations that describe the various equilibria.…”

“…9 also depicts the results for d 2 4:47 Â 10 3 , corre sponding to the absorption of CO 2 into an expanding water sheet. This particular value has been calculated using the equilibrium constant (deduced from Henry's law [45]) and the heat of absorp tion of CO 2 into water at 25°C and at 1 atm [46]. In this special case, the heat of absorption is very small and the increase of tem perature in the solution is essentially negligible.…”

a b s t r a c tThe problem of non isothermal absorption of vapour into freely expanding liquid sheets is addressed in this study. This is done in the context of four models that characterise the coupled heat and mass transfer in the liquid phase: a nonlinear model retaining the effect of sheet growth, an approximate model for slowly increasing mass flow rate in the sheet, a large Lewis number model and finally, a boundary layer model. These models have been numerically or analytically solved and applied to the comparative anal ysis of two different working pairs, LiBr H 2 O and LiNO 3 NH 3 , under conditions representative of adia batic absorption in refrigeration systems. The limits of applicability of each model have been assessed and the sensitivity of the results to the sheet aperture angle, heat of absorption and initial subcooling has also been tested. For equal initial mass fraction and subcooling, the models indicate that Sherwood number and the rate of absorption in laminar expanding sheets for the LiNO 3 NH 3 solution are always superior to those for the LiBr H 2 O solution.

Metastable phenomena on calcite {101̄4} surfaces growing from Sr2+–Ca2+–CO32− aqueous solutions

In situ atomic force microscopy (AFM) experiments, scanning electron microscopy (SEM) imaging and composition analysis, and X-ray diffraction have provided information about the growth, dissolution and transformation processes promoted by SI.2+ -Ca2+ -CO�-aqueous solutions in contact with calcite {1014} surfaces. Experiments have shown a wide variety of surface phenomena, such as the influence of the Sr-bearing newly-formed surface on the subsequent growth (template effect), the growth and subsequent dissolution of surfaces and the nucleation of secondary three-dimensional nuclei on calcite surfaces.These phenomena reveal the metastability of the crystallisation system and are a consequence of the interplay between thermodynamics (the relative stability of the two calcite and aragonite structure solid solutions that can be fOlmed), supersaturation of the aqueous solution with respect to the two possible solid solutions, and the crystallographic control of the surfaces on cation incorporation.
