Why electron affinity of fluorine is less than that of chlorine ?

How would you account for the following : The electron gain enthalpy with negative sign for fluorine is less than that for chlorine, still fluorine is a stronger oxidising agent than chlorine.

Why electron affinity of halogens is the highest ?

Although electron gain enthalpy of fluorine is less negative as compared to chlorine, fluorine is a stronger oxidising agent than chlorine. Why ?

Although electron gain enthalpy of fluorine is less negative as compared to chlorine, fluorine is stronger oxidizing agent than chlorine. Why?

Explain with reason : The negative electron gain enthalpy of oxygen is less than that of sulphur.

Explain: Electron gain enthalpy of chlorine is more negative than fluorine.
