Mechanism and Rate Law 8 The proposed mechanism for a reaction is Cl 2 + H 2 S => HCl + Cl + + HS - Slow Cl + + HS - => HCl + S Fast Which of the following would be a rate law for the reaction? Student Response Value Correct Answer Feedback 1. rate = k[Cl 2 ]0 % 2. rate = k[Cl 2 ][H 2 S] 100% 3. rate = k[H 2 S] 0% 4. rate = k[HCl][S] 0% 5. rate = [Cl + ][HS - ][HCl] 0% Score: 1/1 2. Mechanism and Rate Law 5 The proposed mechanism for a reaction is 1. ClO - (aq) + H 2 O(l) => HClO(aq) + OH - (aq) SLOW 2. I - (aq) + HClO(aq) => HIO(aq) + Cl - (aq) FAST 3. OH - (aq) + HIO(aq) => H 2 O(l) + IO - (aq) FAST Which of the following would be a rate law for the reaction? Student Response Value Correct Answer Feedback 1. rate = k[ClO - ][H
