Inorganic Chemistry
Question 1
In a proccess of Lithium Chloride synthesis, the following
experimental data were collected. Its lattice energy can
be calculated from a Born-Haber cycle.
Ionization energy of Li = +520 kJ mol
Heat to convert Li(s) to Li(g) = +159 kJ mol
Heat of formation of LiCl = -409 kJ mol
Heat to convert Cl2(g) to Cl(g) = +122 kJ mol
Electron affinity of chlorine atoms = -349 kJ mol
(a) Using the state symbols (s), (l), (g) and the symbol for an
electron, e-, write an equation in each case to define the
following terms:
(i) The first ionization energy of lithium.
(ii) The heat of formation of lithium chloride.
(iii) The electron affinity of chlorine.
(iv) The lattice energy of lithium chloride.
