Consider the reaction CI_(2) (aq)+H_(2)S(aq) rarr S(s)+2H^(+)(aq) +2C

1.	Consider the reaction CI_(2) (aq)+H_(2)S(aq) rarr S(s)+2H^(+)(aq) +2CI^(-1)(aq) The rate equation for this reaction is rate = k[CI_(2)] [H_(2)S] Which of these mechanisms is /are consistent with this rate equation ? CI_(2)+H_(2)S rarr H^(+)+CI^(-)+CI^(+)HS^(-) (slow ) CI^(+)+HS^(-)+CI^(-)+S (fas)H_(2)S rarr H^(+)+HS^(-) (fast equilibrium ) CI_(2)+HS^(-) rarr 2CI^(-)+H^(+) +S (slow )
Answer» Neither (i) nor (ii) (i) only (ii) only Both (i) and (ii) Solution :(B) `CI_(2(aq))+H_(2) S_((aq))rarrS_((s))+2H_((aq))^(+)+2CI_((aq))^(-)` `R= K [CI_(2)][H_(2)S]` SINCE RATE of reaction DEPENDS only on the slow step `:.` Mechanism (A) is correct . `CI_(2)+H_(2)S rarr H^(+)+CI^(-)+CI^(+)+HS^(-)` (slow) `CI^(+) +HS^(-)+CI^(-)+S` (fast )
