| Abstract: | The equilibria involving gaseous species over the condensed Ho-Ag system (series I), the condensed Ho-Al-Au system (series II), the condensed Ce-Pd-C system (series III), and the condensed TiP-Rh-C system (series IV) have been investigated by the high temperature mass spectrometric technique. The third law enthalpies and, where possible, the second law enthalpies have been determined for the following reactions: Ho(g) + Ag₂(g) = HoAg(g) + Ag(g), HoAg(g) + Ho(g) = Ho₂(g) + Ag(g), Ho₂(g) = 2Ho(g), Ho(l) + Ho(g) = Ho₂(g), for series I; HoAu(g) + Al(g) = Ho(g) + AlAu(g), for series II; CePd(g) = Ce(g) +Pd(g), CePd(g) + C₂(g) = CeC₂(g) + Pd(g), Ce(g) + 2C(graph) = CeC₂(g), for series III; Rh(g) + C(graph) = RhC(g), Ti(g) + 2C(graph) = TiC₂(g), Rh + 2C(graph) = RhC₂(g), RhC₂(g) + Rh(g) = 2RhC(g), TiC₂(g) + Rh(g) = RhC₂(g) + Ti(g), RhC(g) = Rh(g) + C(g), RhC(g) + Ti(g) = TiRh(g) + C(g), TiC₂(g) + Rh(g) = TiRh(g) + C₂(g), Rh₂(g) + C(g) = RhC(g) + Rh(g), TiRh(g) = Rh(g) + Ti(g), Rh₂(g) = 2Rh(g), for series IV. ... |
