Ewg Effect On Reactivity Of Haloarene

What is the effect of electron withdrawing group at meta position on the reactivity of haloarenes towards substitution reaction?

How can you increase the reactivity of haloarenes towards substitution reaction?

(A): p-Nitrochlorobenzene is more reactive than chlorobenzene in nucleophilic substitution reactions. (R): Electron withdrawing groups like - NO_2 , increase the reactivity of haloarenes in nucleophilic substitution.
