In the Born-Haber cycle for the formation of solid common salt N a C l , the largest contribution comes from
Options
- AThe low ionisation energy of N a
- BThe high electron affinity of C l
- CThe low Δ H v a p of N a s
- DThe lattice energy
Correct answer
D. The lattice energy
Step-by-step solution
According to Born Haber cycle enthalpy of formation is Δ H f = Δ H s u b l . + 1 2 Δ H d i s s . + I E - E A + L E
