Worked Solution & Example Answer:Define the term enthalpy of lattice dissociation. - AQA - A-Level Chemistry - Question 1 - 2022 - Paper 3
Step 1
Define the term enthalpy of lattice dissociation.
Answer
The enthalpy of lattice dissociation is the energy change associated with the separation of one mole of a solid ionic compound into its gaseous ions under standard conditions. This process is endothermic, meaning that energy is absorbed to overcome the electrostatic forces holding the ions together in the solid lattice.
