Which of the following linear plots do you expect for a reaction \(A \longrightarrow\) products if the kinetics are
(a) zero order,
(b) first order, or
(c) second order? [Section 14.4]
Step 1 of 5) Plant nutrients, particularly nitrogen and phosphorus, contribute to water pollution by stimulating excessive growth of aquatic plants. The most visible results of excessive plant growth are floating algae and murky water. What is more significant, however, is that as plant growth becomes excessive, the amount of dead and decaying plant matter increases rapidly, a process called eutrophication (Figure 18.19). The processes by which plants decay consumes O2, and without sufficient oxygen, the water cannot sustain animal life. The most significant sources of nitrogen and phosphorus compounds in water are domestic sewage (phosphate-containing detergents and nitrogen-containing body wastes), runoff from agricultural land (fertilizers contain both nitrogen and phosphorus), and runoff from livestock areas (animal wastes contain nitrogen).Eutrophication. This rapid accumulation of dead and decaying plant matter in a body of water uses up the water’s oxygen supply, making the water unsuitable for aquatic animals.
