Question
Consider the overall reaction: Cl_2 (aq)+H_2S (aq)--> S (s) +2HCl (aq). A proposed mechanism is
Cl_2-->Cl^++Cl^- (slow)
Cl^-+H_2S-->HCl+HS^- (fast)
Cl^++HS^- -->HCl+S (fast)
If this is the correct mechanism, which is the predicted rate expansion?
i.) rate = k[Cl^+][Cl^-]
ii.) rate = k[Cl_2][H_2S]
iii.) rate = k[S][HCl]^2
iv.) rate = k[Cl_2]
