    • Abstract

       

      Molar heat capacities of two hydride ion conductors, namely, CaHCl and CaHBr, were measured by differential scanning calorimetry. The measured molar heat capacity data of these compounds as a function of temperature is given by the following expressions:Cp CaHCl (J K-1 mol-1) = 57.806 + 16.420 x 10-3. T - 1.006 x 106 .T-2 (308–748 K) Cp CaHBr (J K-1 mol-1) = 56.534 + 44.880 x 10-3.T - 1.481 x 106 .T-2 (323–713 K)

      From the above expressions, molar enthalpy increments, entropies and Gibbs energy functions of these compounds were derived and reported.
