Question

Increasing order of Lattice energy . ​

Answer 1

Answer:

1) lattice energy is directly proportional to product of charge of cation and anion and inversely proportional to sum of the radio of anion and cation

Explanation:

1) FeO , Fe2O3

Ans. FeO<Fe2O3

2)BeO , MgO,

Answer 2

Answer:

Lattice energies are highest for substances with small, highly charged ions. Arrange GaP, BaS, CaO, and RbCl in order of increasing lattice energy. Strategy: ... For compounds with ions with the same charge, use the relative sizes of the ions to make this prediction
