• question_answer1)   Consider the reaction: \[C{{l}_{2}}(aq)+{{H}_{2}}S(aq)\to S(s)+2{{H}^{+}}(aq)+2C{{l}^{-}}(aq)\] The rate equation for this reaction is Rate\[=k[C{{l}_{2}}][{{H}_{2}}S]\] Which of these mechanisms is/are consistent with this rate equation? (A) \[\begin{align}   & C{{l}_{2}}+{{H}_{2}}S\to {{H}^{+}}+C{{l}^{-}}+C{{l}^{-}}+H{{S}^{-}}(slow) \\  & Cl+H{{S}^{-}}\to {{H}^{+}}+C{{l}^{-}}+S(fast) \\ \end{align}\] (B) \[\begin{align}   & {{H}_{2}}S\Leftrightarrow {{H}^{+}}+H{{S}^{-}}(fast\text{ }equilibrium) \\  & C{{l}_{2}}+H{{S}^{-}}\to 2C{{l}^{-}}+{{H}^{+}}+S(slow) \\ \end{align}\]       AIEEE  Solved  Paper-2010
