Step 1
Definition of Entropy of Lattice Dissociation
Answer
The enthalpy of lattice dissociation is defined as the enthalpy change when one mole of a solid ionic compound, such as ammonium nitrate, dissociates into its gaseous ions. This process occurs under standard conditions, where the lattice energy is overcome to separate the ions completely.
