Question
The enthalpy change when one mole of an ionic compound forms from its gaseous ions is:
Correct Answer
Option B is the correct answer.
Detailed Explanation
Lattice enthalpy is defined as the enthalpy change when one mole of an ionic solid is formed from its constituent gaseous ions. It is a measure of the strength of the ionic bonds in the lattice.
Hint
This process involves bringing gaseous ions together to form a solid crystal lattice.
