Question: Few values of enthalpies are given below O = - 141 kJ \(mol^{- 1}\) F = - 328 kJ \(mol^{- 1}\) S =...

Few values of enthalpies are given below

O = - 141 kJ mol−1mol^{- 1} F = - 328 kJ mol−1mol^{- 1}

S = - 200 kJ mol−1mol^{- 1} Cl = - 349 kJ mol−1mol^{- 1}

What do these values show?

A

Ionisation enthalpy

B

Bond enthalpy

C

Electron gain enthalpy

D

Hydration enthalpy

Answer

Electron gain enthalpy

Explanation

Solution

: Negative value of electron gain enthalpy of S is more than that of oxygen and for Cl it is more than that of fluorine.
