Explanation Given: Lattice energy of K 2 O ( s ) ( Δ H l a t t i c e K 2 O ( s ) ) is 2238 kJ . First electron affinity of O ( g ) ( E 1 ( O ) ) is − 141 kJ . Refer Appendix C Energy of formation of K 2 O ( s ) ( Δ H f K 2 O ( s ) ) is − 363.2 kJ . Energy of formation of K ( g ) ( Δ H f K ( g ) ) is 89.99 kJ . Energy of formation of O ( g ) ( Δ H f O ( g ) ) is 247.5 kJ . Refer Figure 7.10 First ionization energy of K ( g ) ( I 1 ( K ) ) is 419 kJ . Lattice energy means the energy required to break one mole of solid ionic compound into its gaseous ions. The breaking of one mole of K 2 O into its components gaseous ions that is K + ( g ) and O 2 − ( g ) is represented as, K 2 O ( s ) → 2K + ( g ) + O 2 − ( g ) It involves the following steps. The separation of one mole K 2 O into two moles of K ( s ) and 1 mole of O ( g ) . The energy required is equal to the energy of formation of K 2 O . K 2 O ( s ) → 2 K ( s ) + 1 2 O 2 ( g ) ( Δ H f K 2 O ( s ) ) K ( s ) is converted to its gaseous form for which energy is required since sublimation is an endothermic process. The energy required is equal to the energy of formation of K ( g ) K ( s ) → K ( g ) ( Δ H f K ( g ) ) Dissociation of 1 2 moles of O 2 ( g ) into O ( g ) for which energy required is the energy of dissociation of 1 2 moles of O 2 ( g ) 1 2 O 2 ( g ) → O ( g ) ( Δ H f O ( g ) ) Formation of gaseous K + ions from gaseous ( K ) by removal of electrons
