Q# Question Text 3) Scoring Scheme: 3-3-2-1 Which of the following values would you expect for the ratio of half-lives for a reaction with starting concentrations of 0.05M and 0.01M, t 1/2 (0.05M) / t 1/2 (0.01M), if a reaction is known to be zero order? Your Answer: d. 5 You Scored 3 points out of 3 Possible 4) Scoring Scheme: 3-3-2-1 Which of the following values would you expect for the ratio of half-lives for a reaction with starting concentrations of 0.05M and 0.01M, t 1/2 (0.05M) / t 1/2 (0.01M), if a reaction is known to be first order? Your Answer: b. 1 You Scored 3 points out of 3 Possible 5) Scoring Scheme: 3-3-2-1 Which of the following values would you expect for the ratio of half-lives for a reaction with starting concentrations of 0.05M and 0.01M, t 1/2 (0.05M) / t 1/2 (0.01M), if a reaction is known to be second order? Your Answer: e. 0.2 You Scored 3 points out of 3 Possible 6) Data Entry - No Scoring What value do you calculate for the ratio t 1/2 (0.05M) / t 1/2 (0.01M) from your experimentally measured half-lives at 55 °C? ratio = Your Answer: 1 No Points Possible 7) Scoring Scheme: 3-2-1-1 Given your experimentally measured ratio of half-lives for the two different concentrations, select the concentration dependence that best describes your experimental ratio. Your Answer: b. half-life is independent of concentration You Scored 3 points out of 3 Possible 8) Scoring Scheme: 3-2-1-1 Based on the ratio of half-lives for the two different concentrations that you determined, and comparing the experimental ratio with the theoretical ratios for kinetic orders 0, 1, and 2, which order does this reaction exhibit? Your Answer: b. first order You Scored 3 points out of 3 Possible 10 ) Data Entry - No Scoring In part II of the experiment, you and your partner measured the half-life of the reaction at 5 different
