WebLattice Energy is used to explain the stability of ionic solids. Some might expect such an ordered structure to be less stable because the entropy of the system would be low. However, the crystalline structure allows each ion to interact with multiple oppositely charge ions, which causes a highly favorable change in the enthalpy of the system. WebThe enthalpy change for the reaction that forms products C+D directly \((\Delta H_{x})\) will be the same as the sum of the enthalpy changes for the production of C+D via an indirect route where ...
