| Abstract: | Resolution of excess entropy of many types of transitions and estimation of standard entropy at 298.15K of compounds, for which experimental entropies have not yet been measured, depend on the reliable estimationof the lattice entropy. By taking into account the effects of cation mass and molar volume of the rare-earth compounds, the following formula is proposed |
