Water bond dissociation enthalpy

The use of isotopes has found surprisingly few applications in the determination of mechanisms of dehydrations. Below the temperature of appreciable water evolution, DjO/HjO exchange could, in principal be used to measure, in partially decomposed salt, e quantities of water held at surface sites of different reactivities, i.e. water physically adsorbed, chemisorbed, within amorphous phases and at the reaction interface. Similarly, kinetic isotope effects in dehydration reactions have not been extensively investigated. If corresponds to the enthalpy of dissociation, the substitution of a deuterium bond for a hydrogen bond could result in a change of the magnitude of E. ... [Pg.261]

The mean bond enthalpy for the stepwise dissociation of both O-H bonds in water is (499 + 428)72 = 463.5 kjmol-h... [Pg.237]
