Use the Born-Haber cycle to calculate the lattice energy of KCl(s) given the following data: $\Delta$ H(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
$\Delta{H}^{\circ}_f$ (KCl(s) ) = -435.7 kJ/mol

Question

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

\Delta

H(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

\Delta{H}^{\circ}_f

(KCl(s) ) = -435.7 kJ/mol
