Born- Haber calendar method 1. The wicket gate henry of atomic number 12 chloride, MgCl2, can be decided using a Born-Haber cycle and the following enthalpy diversitys. | figure of process |Enthalpy transfigure/kJ mol-1 | |Enthalpy change of administration of MgCl2 |-641 | |Enthalpy change of atomisation of magnesium |+148 | | first-class honours degree ionization zip fastener of magnesium |+738 | | secondment ionization energy of magnesium |+1451 | |Enthalpy change of atomization of chlorine |+123 | |Electron similarity of chlorine |-349 | a) Define, using an comparability 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) formulate why the lattice enthalpy of NaBr is much less heat-releasing 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 plentiful essay, order it on our website:
