NEET Chemistry Ionic Bond MCQ Question
What is the lattice enthalpy of a compound if 500 kJ of energy is required to separate half a mole of the compound into its gaseous ions?
1000 kJ mol⁻¹
250 kJ mol⁻¹
500 kJ mol⁻¹
2000 kJ mol⁻¹
Correct Answer
Detailed Explanation
Lattice enthalpy is defined as the energy required to completely separate one mole of a solid ionic compound into its gaseous ions. If 500 kJ is needed for half a mole, then for one mole, it would be double, i.e., 1000 kJ mol⁻¹.
