Problem

Suppose that for the reaction K + L → M, you monitor the production of M over time, and then plot the following
graph from your data:

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