Suppose that for the reaction \(\mathrm{K}+\mathrm{L} \longrightarrow \mathrm{M}\), you monitor the production of M over time, and then plot the following graph from your data:

(a) Is the reaction occurring at a constant rate from t = 0 to t = 15 min?

(b) Is the reaction completed at t = 15 min?

(c) Suppose the reaction as plotted here were started with 0.20 mol K and 0.40 mol L. After 30 min, an additional 0.20 mol K are added to the reaction mixture. Which of the following correctly describes how the plot would look from t = 30 min to t = 60 min?

(i) [M] would remain at the same constant value it has at t = 30 min,

(ii) [M] would increase with the same slope as t = 0 to 15 min, until t = 45 min at which point the plot becomes horizontal again, or

(iii) [M] decreases and reaches 0 at t = 45 min. [Section 14.2]
