The lattice energy of Rubidium Oxide (Rb2O) is approximately -610 kJ/mol. This value represents the energy released when one mole of solid Rb2O is formed from its constituent ions in the gas phase.

Why is the lattice energy of potassium bromide more exothermic than the lattice energy of rubidium iodide?

The lattice energy of potassium bromide is more exothermic than that of rubidium iodide because potassium and bromine have smaller atomic sizes and higher charges, which leads to stronger ionic bonding in potassium bromide. Rubidium and iodine have larger atomic sizes and lower charges, resulting in weaker ionic bonding in rubidium iodide. The stronger ionic bonding in potassium bromide requires more energy to break, resulting in a more exothermic lattice energy.

Why is themite reaction highly exothermicexplain in terms of lattice energy?

The thermite reaction, which typically involves the reaction between aluminum powder and a metal oxide like iron(III) oxide, is highly exothermic due to the significant release of energy associated with the formation of metallic bonds and the destruction of the oxide's lattice structure. When the metal oxide is reduced, the strong ionic bonds in the lattice are broken, and new metallic bonds are formed, which have lower energy. The energy released from these new bonds, combined with the energy required to break the initial bonds (lattice energy), results in a large net release of heat. This energy release drives the reaction forward and contributes to the intense heat and light generated during the process.
