In nucleophilic aromatic substitution reactions that proceed by the nucleophilic addition-elimination mechanism, the reaction rate increases as the electronegativity of the halogen leaving group increases: Ar-I < Ar-Br < Ar-CI < Ar-F. Which step does this suggest is the rate-determining step of the mechanism-the addition step or the elimination step? Explain.
