NEETChemistryChemical Bonding and Molecular Structure
Which enthalpy change is specifically mentioned as being compensated for by the enthalpy of lattice formation in the case of NaCl(s)?
Options
- AIonization enthalpy
- BElectron gain enthalpy
- CSum of ionization enthalpy and electron gain enthalpy
- DEnthalpy of fusion
Correct answer
C. Sum of ionization enthalpy and electron gain enthalpy
Step-by-step solution
The sum of the ionization enthalpy for Na+(g) and the electron gain enthalpy for Cl- (g) is more than compensated for by the enthalpy of lattice formation of NaCl(s).
