What is lattice enthalpy in the context of ionic compounds?

Options

  1. AThe enthalpy change when an ionic compound dissolves in water.
  2. BThe enthalpy change when an ionic compound forms in a chemical reaction.
  3. CThe enthalpy change when one mole of an ionic compound dissociates into its ions in the gaseous state.
  4. DThe enthalpy change when an ionic compound is heated to its melting point.

Correct answer

C. The enthalpy change when one mole of an ionic compound dissociates into its ions in the gaseous state.

Step-by-step solution

Lattice enthalpy is the enthalpy change when one mole of an ionic compound dissociates into its ions in the gaseous state.
