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 -0.048 s. What is the concentration of A (in M) after 13.0 s if [A], 0.20 M? Answer: For the reaction D A+ C when 1/[D] is plotted versus the time in seconds, a straight line is obtained whose slope is 0.043 M-s-.. What is the concentration of D (in M) after 22.0 s if [D]o = 0.20 M? Hint given in feedback Answer:
