15. Chemical Kinetics

What is the overall order of the reaction expressed with the rate law, rate = k[A]²[B]?

An automotive fuel injector dispenses a fine spray of gasoline into the automobile cylinder, as shown in the bottom drawing here. When an injector gets clogged, as shown in the top drawing, the spray is not as fine or even and the performance of the car declines. How is this observation related to chemical kinetics? [Section 14.1]

Consider the following graph of the concentration of a substance X over time. Is each of the following statements true or false? (d) As time progresses, the curve will eventually turn downward toward the x-axis. [Section 14.2]

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:

(b) Is the reaction completed at t = 15 min? [Section 14.2]
