ChemistryChemical KineticsJEE Main 2010

Consider the reaction :

+ → S(s) + +

The rate equation for this reaction is rate = Which of these mechanisms is/are consistent with this rate equation? (A) Cl_2 + H_2 \to H^+ + Cl^- + Cl^+ + HS^- (slow) (fast) (B) (fast equilibrium) (slow)

Answer: (4)

Solution

In A (with in the slow step, as intended), the rate-determining step involves one and one , so rate =
