(1) Table 1 lists a number of standard enthalpies that are relevant to the Born-Haber cycle of KCI. Table 1: Selected standard enthalpies Process AH /kJ mol-1 Sublimation of K(s) +89 lonisation of K(9) +418 Dissociation of Cl2(g) +244 Electron attachment to Cl(9) -349 Formation of KCI(S) -437 (a) (1) Explain how Hess's law is applied when a Born-Haber cycle is set up. (2 marks) (1) What is the definition of lattice enthalpy? (2 marks) (1) Determine the lattice enthalpy of potassium chloride (KCl) by constructing a Born-Haber cycle. Start by writing out the reaction equations for each process listed in Table 1
