![]() ![]() 2\nThus here the trend of lattice energy is due to charge of the ion. Hence due to greater charge, the lattice energy of SrO is greater than SrCl. It is known that the lattice energy is directlyproportional to the charge of the ion i.e greater the charge of the ion larger will be the latticeenergy. Hence due to greater charge, the lattice energy of BaO is greater than KF.Thus here the trend of lattice energy is due to charge of the ion.Step-3 (c) SrO > SrCl 2The charge of oxide ion is -2 and chloride ion is -1. road closures in boston lincolnshire Navigation. Na, Rb and Cs all are present in group 1A andthe trend of atomic size is Na KFThe charge of oxide ion is -2 and fluoride ion is -1. 2Solution 8.26Lattice energy is defined as the amount of energy release to break an ionic solid to formcorresponding gaseous ions.The two main factors affecting lattice energy are charge and radius of the bonded ions.Lattice energy Charge of the ion (Greater the charge larger will be the lattice energy)Lattice energy Size of the ionaller the size of the ions larger will be the lattice energy)Step-1(a) NaCl > RbBr > CsBrAs we go down a group the atomic size increases. The crystal lattice energy has influence on other physical and chemical properties: solubility, volatility, melting temperature (the higher lattice energy, the higher melting temperature), hardness, etc. Other salt like NaCl dissolve in water because hydration energy is much more than its lattice energy. LiF is insoluble in water because its lattice energy is higher than hydration energy. The lattice energy is usually given in kilojules per mole (kJ/mol). Lattice energy is the amount of energy which bound the crystal lattice. Problem 8.26Which of the following trends in lattice energy is due to differences in ionic radii(a) NaCl > RbBr > CsBr, (b) BaO > KF, (c) SrO > SrCl. The lattice energy trend is a pattern that describes the changes in lattice energy as the properties of the ions in an ionic compound are varied. The lattice energy is the total potential energy of the crystal.
