Thus point 2 addresses point 2 in your question, K is bigger than Li, hence the separation is bigger in KF than LiF, hence KF has a lower lattice energy than LiF. The first point explains why MgO has a higher lattice energy than NaF.

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 Web1. The rate of condensation is equal to the rate of evaporation. 2. The fraction of molecules with enough energy to escape the liquid surface depends on the liquid surface area. 3. The vapor pressure is independent of the temperature. 1 only. If more ice is added to an ice-water mixture at equilibrium.
