Unformatted text preview: 4. (10 points) Determine whether the theoretical cesium (II) fluoride will spontaneously decompose into cesium fluoride: CsF 2 (s) CsF(s) + F 2 (g) by first determining the H o f for CsF 2 (s) (Cs(s) + F 2 (g) CsF 2 (s)) using a Born Haber cycle and the following data, as needed: Lattice energy for CsF 2 is 2250 kJ mol-1 ; Cs 1 st IE 382 kJ mol-1 ; Cs 2 nd IE 2430 kJ mol-1 ; Bond energy of F 2 = 155 kJ mol-1 ; EA of F is -328 kJ mol-1 ; Cs(g) H o f = 76 kJ mol-1 ; CsF(s) H o f = -554 kJ mol-1 . 5. (2 points) For the alkaline earth metals (except Be) which will have the most insoluble hydroxide? Why?...
