WebCorrect option is C) Lattice energy is directly proportional to charge of the ion and size of ions.Lattice energy is inversely proportional to size of ion. As F − is smaller in size than Cl − so NaF has greater lattice energy than NaCl and as Na + is smaller in size than K + so NaCl has greater lattice energy than KCl. So RbCl WebKI,4. CsI. Q. Solubility of CsF is more than CsI. Which factor may explain it? Q. Assertion : CsI is insoluble in water. Reason: Hydration energy of Cs+ and I− ions are higher than lattice energy. Q. In going from CsF to CsI, the melting point of the crystal decreases. If true enter 1, else enter 0. WebAug 15, 2024 · Lattice enthalpy is a measure of the strength of the forces between the ions in an ionic solid. The greater the lattice enthalpy, the stronger the forces. Those forces are only completely broken when the ions are present as gaseous ions, scattered so far apart that there is negligible attraction between them. greg crawford
