Electron Gain Enthalpy

The electron gain enthalpies of halogens are as given below: F =- 332, CI =- 349, Br =- 324, I =- 295 kJ mol^(-1) . The less negative value for F as compared to that of CI is due to:

Statement-1: Second electron gain enthalpy of halogens is always positive. Statement-2: Fluorine has most negative electron gain enthalpy.

The absolute value of the electron gain enthalpy of halogens satisfies :

Electron gain enthalpy will be positive in
