4. The common oxidation number for an alkaline earth metal is +2. (a) Using the Born-Mayer equation (for determining the lattice enthalpy) and a Born-Haber cycle (draw it), show that CaCl is an exothermic compound (negative AHf). Make a reasonable prediction to estimate the ionic radius of Ca (explain your reasoning). The sublimation (atomization) enthalpy for Ca(s) is 178 kJ/mol. (b) Show that an explanation for the non-existence of CaCl can be found in the enthalpy change for the reaction below. The AHf for CaCl2(s) is -190.2 kcal/mol. 2 CaCl(s) → Ca(s) + CaCl2(s)
2a. Determine the theoretical lattice energy using the Kapustinskii's equation. 1.202 x 105 VZ*Z¯ U = 34.5 r* + r r* + r Ca2+ = 114 pm I = 206 pm b. Compare your answer to the experimental lattice energy of -1971 kJ/mol.
