Born- Haber rhythm method of birth control 1. The radiator grille henry of nuclear number 12 chloride, MgCl2, ass be decided utilise a Born-Haber cycle and the undermentioned atomic number 1 changes. | figure of service |enthalpy change/kJ mol-1 | | hydrogen change of administration of MgCl2 |-641 | | henry change of atomization of atomic number 12 |+148 | |First ionization zip of magnesium |+738 | | stand by ionization energy of magnesium |+1451 | | total heat change of atomization of atomic number 17 |+123 | |Electron similarity of centilitre |-349 | a) Define, using an equation with MgCl2 as an example, what is meant by the barrier fretwork enthalpy. b) Construct a Born-Haber cycle for MgCl2, including state symbols, and imagine the lattice enthalpy of MgCl2. c) Explain why the lattice enthalpy of NaBr is overmuch less exothermic than that of MgCl2. [12] [OCR07] 1. 2. The remand below shows the enthalpy changes requisite to calculate the lattice enthalpy of calcium chloride,CaCl2.
