calculate the lattice energy of NaCl crystal from the following data by the use of Born-Harbor cycle.

sublimation energy(s) = 108.7kJ mol^-1

Dissociation energy for Cl₂ (D)= 225.9 kJ mol^-1

lonization energy for Na(g)(I)= 489.5 kJ mol^-1

Electron affinity for CI(g)E = -351.4kJ mol^-1

Heat of formation of NaCI(?H_p)= -414.2 kJ mol^-1
