the electron affinity of fluorine is less than chlorine . still its more reactive than chlorine due to the following reason . 
1- the low dissociation energy of f2 molecule , and high hydration energy of f- ion , more than compensate for the low electron affinity fluorine , the oxidising power of fluorine is more than chlorine . 
2- the electronegativity of fluorine is more than that of chlorine . 
DUE TO THIS ABOVE STATED REASONS , F2 IS MORE REACTIVE THAN CL2 . 
HOPE U CLEAR WITH THIS 
ALL THE BEST ..
