Homework Statement
The proposed mechanism for a reaction is
Cl2 => 2 Cl (Fast)
Cl + H2S => HCl + HS (Slow)
Cl + HS => HCl + S (Fast)
Which of the following would be a rate law for the reaction?
The Attempt at a Solution
From other questions I've done the rate law for the reaction is always the slow step or rate-determining step. My answer was;
k[Cl-][H2S]
But the answer is k[Cl2]1/2[H2S]
I don't really understand how they got that answer. Any help would be appreciated!
