Consider the reaction :

Cl2(aq)+H2S(aq)→S( s)+2H+(aq)+2Cl−(aq)

The rate equation for this reaction is rate =k[Cl2][H2S]
Which of these mechanisms is/are consistent with this rate equation?
(A) Cl2+H2S→H++Cl−+Cl++HS−(slow)
Cl++HS−→H++Cl−+S‌ (fast) ‌
(B) H2S⇔H++HS−(fast equilibrium)
Cl2+HS−→2Cl−+H++S‌ (slow) ‌
