Question

Use the following data to calculate standard lattice enthalpy for NaBr .


Given that : Change in enthalpy of sublimation Hsub for sodium metal =108.4kJ/mol ,

Ionisation enthalpy of sodium = 496kJ/mol ,electron gain enthalpy of bromine = -325

kJ/mol
bond dissociation enthalpy of bromine =192 kJ /mol , Standard enthalpy of

formation of NaBr (s) = -360.1 kJ / mol.​

Answer 1

Answer:

Given that : Change in enthalpy of sublimation Hsub for sodium metal =108.4kJ/mol ,

Ionisation enthalpy of sodium = 496kJ/mol ,electron gain enthalpy of bromine = -325

kJ/mol

bond dissociation enthalpy of bromine =192 kJ /mol , Standard enthalpy of

formation of NaBr (s) = -360.1 kJ / mol.
