This equation indicates that the two factors that contribute to lattice enthalpy are magnitude of charge and the distance between them. Since the lattice formation enthalpy is electrostatic in nature, too, we can say that it depends on similar factors such as the charges of the ions, their ...

system. Ice consists ofwater moleculesbonded to each other in a crystal lattice. As ice melts, molecules gain energy, spread further apart, and lose structure to form a liquid. Similarly, the phase change from a liquid to a gas, as from water to steam, increases the energy of the system...
Applications of Hess's Law In addition to calculating the enthalpy of a reaction rather than directly measuring it, Hess's law is used to: Find electron affinities based on theoretical lattice energy. Calculate heat change of phase transitions. ...
Gong proposed the intrinsic correlation between the elastic moduli of crystals and their lattice constants (Fig.2.5). The elastic modulusG, which represents the energy density for causing material deformation, is expressed by the formulaU/b3, wherebandUdenote the lattice constant and the deformation...
