6) Construct a graphical Born-Haber cycle for the formation of SrCl2(s). Explicitly label each transformation according to the chemical / physical change involved, and the thermochemical descriptor (i.e. AHatomization, AH lattice, IE, EA etc.). Relevant thermochemical data (in kJ/mol): For Sr: Enthalpy of sublimation: 164. IE₁: 549; IE2: 1064. For Cl: Electron affinity of Cl: -349. Enthalpy of dissociation for Cl₂: +243. Lattice energy of SrCl₂: -2150. Using these data, calculate the enthalpy of formation of SrCl₂.
