Question 8 1.25 / 1.25 pts Consider the overall reaction: 2 X 2 Y + Z 2 2 X 2 YZ which has an experimentally determined rate law of: rate= k[X 2 Y][Z 2 ]. Which of the following are possible mechanisms for the reaction? Step 1: 2 X 2 Y + Z 2 → 2X 2 YZ (slow) Step 1: X 2 Y + Z 2 X 2 YZ + Z (fast) Step 2: X 2 Y + Z → X 2 YZ (slow)
Step 2: X 4 Y 2 + Z 2 → 2 X 2 YZ (slow) Step 1: Z 2 → Z + Z (slow) Step 2: X 2 Y + Z → X 2 YZ (fast) Step 3: X 2 Y + Z → X 2 YZ (fast) None of the above Question 9 1.5 / 1.5 pts Phosgene (Cl 2 CO), a poison gas used in World War I, is formed by the reaction of Cl 2 and CO. The proposed mechanism for the reaction is Cl 2 2 Cl (fast,equilibrium) Cl + CO ClCO (fast,equilibrium) ClCO + Cl 2 → Cl 2 CO + Cl (slow) Based on this mechanism, determine the rate law for the overall reaction. Express your answer in terms of k and the necessary concentrations (ex: k[X][Y]^2). Use brackets around the concentrations and the caret symbol prior to the exponent. Do not include any multiplication signs. Type in subscripts as normal numbers (ex: Cl2, Cl2CO). Rate = Correct! k[Cl2]^3/2[CO
k[CO][Cl2]^(3/2) k[CO]^1[Cl2]^(3/2) Quiz Score: 9 out of 10
