| 释义 | > as lemmasBorn–Haber cycle As a modifier. Designating a cycle of reactions which describe the formation of an ionic compound from its elements by means of a series of steps, such that the energy change for one step of the cycle can be calculated from the energy changes associated with the other steps (chiefly in Born–Haber cycle). Also: of, relating to, or calculated with reference to such a cycle.Born–Haber cycles are used esp. for calculating lattice energy. ΚΠ 1931 Jrnl. Amer. Chem. Soc. 53 1188 The fifth part..takes up such topics as the Born–Haber cycle, polar and non-polar compounds, etc. 1969 Jrnl. Electrochem. Soc. 116 354/1 Since the Born-Haber lattice energies are not true thermochemical values for the case of oxides, it is not valid to compare them with the theoretical lattice energies. 1978 G. C. Hill & J. S. Holman Chem. in Context xi. 157 The lattice energy for sodium chloride can now be obtained since all other values in the Born–Haber cycle can be determined experimentally. 2010 J. E. McMurry & R. C. Fay Gen. Chem. iv. 115 A similar Born–Haber cycle for the reaction of magnesium with chlorine shows the energy changes involved in the reaction of an alkaline earth element. < as lemmas |
