alleryWhat is the lattice enthalpy of sodium chloride?
A188 kJ per mole
B388 kJ per mole
C988 kJ per mole
D788 kJ per mole
Answer & Solution
Correct answer: D. 788 kJ per mole
1. The value is quoted directly as a worked example.
2. It is well under a thousand kilojoules per mole.
3. The lattice enthalpy of NaCl is 788 kJ per mole.
4. So the answer is 788 kJ per mole.
