Question

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)
(a) B only (b) Both A and B
(c) Neither A nor B (d) A only
