✦ Synopsis

Heat capacities of PbI , ZnCl , and AsI have been determined by adiabatic shield 2 2 3 calorimetry from T s 5 K to T s 350 K. No anomalous regions were found in the heat capacity of PbI and ZnCl . Two anomalous regions were found in the heat capacity of AsI : 2 2 3 one small sharp peak at T s 161 K, and the other, a broad region from about T s 225 K to T s 290 K. The thermodynamic properties have been evaluated and the values of molar heat capacity, entropy, and enthalpy at T s 298.
