see..
Size of chlorine is bigger than fluorine and it has vacant d orbital due to which it can withhold a electron but size of fluorine is very less and it also not have any vacant d orbital therefore it cannot withhold a electron that is why electron gain enthaloy of chlorine is higher than fluorine ..

Answer:
Due to its small size, the electron–electron repulsions in the relatively compact 2p-sub-shell are comparatively large, and hence, the incoming electron is not accepted with the same ease as is the case with larger Cl atom. Consequently, electron gain enthalpy of Cl is more negative than that of F.
