✦ Synopsis

standard molar enthalpy of formation of Y Ba Cu O at T s 298.15 K has 2 4 7 14.916 0 Ž . been determined by solution calorimetry to be: ⌬ H Y Ba Cu O , cr, 298.15 K s f m 2 4 7 14.916 . y1 Ž . y 5465.7 " 7 kJ mol . During the experiment the molar enthalpies of reaction of the Y Ba Cu O high-temperature superconductor and metallic yttrium with 1.07 N HCl 2 4 7 14.916 have been measured in a hermetic rotating calorimeter equipped with an isothermal jacket. ᮊ
