1. Using the Born-Landé equation and the Kapustinskii equation, calculate the lattice enthalpy of cesium chloride. Cesium: 181 and Chloride: 167

2. Construct a Born-Haber cycle to calculate the first ionization energy for cesium. (should you use the results from the Born-Landé or the Kapustinskii equation). 3.

3. Calculate the lattice energy of MgF2 (Born Haber). Use the Kapustinskii Equation to calculate the radius of the Mg2+ ion. Hint – you will need to solve a quadratic (set ro = x and solve the quadratic for x =which equals (r(Mg2+) + r(F-)). Compare your value for the Mg2+ radius to the accepted value found in tables.
