Use the Born-Haber cycle to calculate the lattice energy of KCl(s) given the following data:

ΔH(sublimation) K = 79.2 kJ/mol

I1 (K) = 418.7 kJ/mol

Bond energy (Cl-Cl) = 242.8 kJ/mol

EA (Cl) = 348 kJ/mol

ΔH°f (KCl(s)) = -435.7 kJ/mol

a. -165 kJ/mol

b. 288 kJ/mol

c. 629 kJ/mol

d. -707 kJ/mol

e. -828 kJ/mol
