Question

Use the Born-Haber cycle to calculate the lattice energy of NaF. (Hsub for sodium is 107.5 kJ/mol, IE1 for sodium is 496 kJ/mol, EA1 for fluorine is 328 kJ/mol, the bond energy of F2 is 159 kJ/mol, Hf for NaF is 576.6 kJ/mol .) Express your answer as an integer.

Answer 1

U = - 931.6kJ/mol

Step-by-step explanation:

Born-Haber cycle is used to calculate the lattice enthalpy indirectly by making use of Hess law of enthalpy cycle
