Born- Haber calendar method 1. The grill henry of atomic number 12 chloride, MgCl2, can be decided using a Born-Haber cycle and the following enthalpy varietys. | figure of process |Enthalpy modification/kJ mol-1 | |Enthalpy change of administration of MgCl2 |-641 | |Enthalpy change of atomization of magnesium |+148 | | offshoot ionization goose egg of magnesium |+738 | | scrap ionization energy of magnesium |+1451 | |Enthalpy change of atomization of chlorine |+123 | |Electron similarity of chlorine |-349 | a) Define, using an equality with MgCl2 as an example, what is meant by the barrier lattice enthalpy. b) Construct a Born-Haber cycle for MgCl2, including state symbols, and imagine the lattice enthalpy of MgCl2. c) beg off why the lattice enthalpy of NaBr is much less exothermal than that of MgCl2. [12] [OCR07] 1. 2. The table below shows the enthalpy changes needed to calculate the lattice enthalpy of calcium chloride,CaCl2.
| execute |Enthalpy change/kJ mol-1 | |First ionization energy of calcium |+590 | |Second ionization energy of calcium |+1150 | |Electron proportion of chlorine |-348 | |Enthalpy change of formation for calcium chloride...If you want to get a plenteous essay, order it on our website:
