The electron enthalpies of halogenes become less negative in the order F>Cl> Br> I. Comment on the statement.

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

Electron gain enthalpy of chlorine is more negative as compared to fluorine.

The negative electron gain enthalpy of F is less/more than Cl.

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?

Would you expect the second electron gain enthalpy of O. as positive, more negative or less. negative than the first ? Justify your answer.

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.

STATEMENT-1: We cannot add the electrode potential in order to get electrode potential of third electrode if no. of moles of electrons exchanged are not same. STATEMENT-2: Electrode potential is an extensive property
