The lattice enthalpy of KCI is positive, indicating that it takes energy to break the ions apart in KCI. However, the dissolution of KCI in water is an exothermic process. Identify all particle-particle interactions that contribute significantly to the exothermic dissolution process being exothermic. For each interaction, include the particles that interact and the specific type of intermolecular force between those particles.
