Question:

The measured molar heat capacities for crystalline KCl are as follows at the indicated temperatures:

50. T (K) Cy m (J/mol K) 100. 175 250. 21.1 39.0 46.1 48.6

a. Explain why the high-temperature limit for C_V is apparently twofold greater than that predicted by the Dulong€“Petit law.

b. Determine if the Einstein model is applicable to ionic solids. To do this uses the value for C_V at 50. K to determine Î˜_V, then uses this temperature to determine C_V at 175 K.
