Question 11 Not yet answered Marked out of 1.00 For the first-order rate of reaction A -->B+C, what is the concentration of A (in M) after 56.0 s if [A]. = 0,40 M and k = 0.037 s-?? Answer: Question 12 Not yet answered Marked out of 1.00 For a first order reaction, the initial reactant concentraion is 0.53 M. After 32.7 s, the concentration is 0.13 M. What is k in sl? Answer:

Question 13 Not yet answered Marked out of 1.00 For a first order reaction, the initial reactant concentration, [A]o, is 0.81 M. After 17.2 s, the concentration is 0.52 M. What is [A] after 68 s? Hint given in feedback Answer: Question 14 Not yet answered Marked out of 1.00 For the reaction A +B+C when [A] is plotted versus the time in minutes a straight line is obtained whose slope is -0.019 M/min. What is the concentration of A (in M) after 31.00 min if [Al. = 0.70 M? Answer:

Question 15 Not yet answered Marked out of 1.00 For the reaction A+B+C, when the natural log of [A] is plotted versus the time in seconds a straight line is obtained whose slope is -0.067 s 1. What is the concentration of A (in M) after 47.0 sif [A]. = 0.10 M? Answer: Question 16 Not yet answered Marked out of 1.00 For the reaction D → A+ C when 1/[D] is plotted versus the time in seconds, a straight line is obtained whose slope is 0.047 Mis? What is the concentration of D (in M) after 47.0 s if [D]. = 0.80 M? Hint given in feedback Answer:

Question 17 Not yet answered Marked out of 100 For a certain reaction, when the natural log of the reactant concentration is plotted against the time in seconds a straight line is obtained. What is the reaction order? Select one: O a zero-order b. first-order O c. second-order Question 18 Not yet answered Marked out of 1.00 For the above reaction, the slope is -0.016. What are the units of the slope and what is k? Note, logs are unitless! Additional hint given in feedback. Select one or more: O a units: M/s O b. units: 1/5 O c. units: 1/(Ms) O d. k = -0.016 M/s ek = +0.016 M/S O f.k=-0.016 1/5 09. k = +0.016 1/8 h.k = -0.016 1/(Ms) I. k = +0.016 1/(Ms) ОО
