1. a. Draw Born-Haber cycle for the formation of strontium chloride
b.Use the following data to calculate the enthalpy of formation of strontium chloride. You must write all
thermochemical equations for the steps of the cycle.
The enthalpy of sublimation of strontium = + 164 kj/mole
First ionization energy for strontium = + 549 kj/mole
Second ionization energy for strontium = + 1064 kj/mole
The enthalpy of dissociation of chlorine, Cl2 = + 243 kj/mole
The electron affinity of chlorine, Cl = - 349 kj/mole
Lattice energy of strontium chloride = - 2150 kj/mole Answer= - 828 kj
