A general mechanism for aromatic electrophilic substitution reaction

1.	A general mechanism for aromatic electrophilic substitution reaction is. (K_(1) and K_(2) are rate constant for the forward reaction) also C-D bond in harder to break than a C-H bond, and consequently reaction in which C-D bond broken proceed more slowly than the reaction in which C-H bond are broken. However experimetns reveal that nitration of C_(6)H_(6) and C_(6)D_(6) proceeds at equal rates while the same is not true for sulphonation of C_(6)H_(6) and C_(6)D_(6). Q. In the nitration reaction
Answer» `k_(1)=k_(2)` `k_(1) gt k_(2)` `k_(1) lt k_(2)` `k_(1) UNDERSET(~)(-) k_(2)` SOLUTION :In electrophylic substitutions step 1 is RDS.
