The standard enthalpies offormation oxides of the fourth period eleemtns of the d block areas follows:
TiO VO MnO FeO CoO NiO CuOZnO
-518 -431 -385 -264 -239 -241-155 -348
a)write a general equationsuitable for calculating the lattice energy of any of these oxides,based on theoritical data
b)Find the lattice energies ofTiO, CuO, and ZnO
c) Overall the most dissimlar enthalpy values are those of TiOand CuO; the most dissimilar enthaly values of neighvoring oxidesare those of CuO and ZnO. Which thermodynamic factor is apparentlyrepsonsible for each of these dissimilarities? d)What factor oftheoritcial lattice energy calculations is most repsonsible forsubstantial change in lattice eneregies between TiO and CuO?
