$Cl_2(aq) + H_2S(aq) \to S(s) + 2H^+(aq) + 2Cl^-(aq)$ rate law is $r = K[Cl_2][H_2S]$
then which of these mechanism is/are consistent with this rate law
$(A)\, H_2S \rightleftharpoons H^+ + HS^-$ (fast)
$Cl_2 + HS^-\to 2Cl^-+ H^+ + S$ (slow)
$(B)\, Cl_2 + H_2S \to H^+ + Cl^-+ Cl^+ + HS^-$ (slow)
$Cl^+ + HS^-\to H^+ + Cl^-+ S$ (fast)
