Answer»

Use the following data to calculate the lattice energy of caesium oxide.
Enthalpy of formation of caesium oxide = 233 kJ mol1
Enthalpy of sublimation of Cs=+78 kJ mol1
First ionization energy of Cs=+375 kJ mol1
Enthalpy of dissociation of O2 (g)=494 kJ mol1of O2 molecules
First electron affinity of O=141 kJ mol1 of O atoms
Second electron affinity of O=+845 kJ mol1 of O1 ions
