Chapter 16 - Kinetics: Rates and Mechanisms of Chemical Reactions

Collision frequency

________, and therefore reaction rate, are also affected by the physical condition of the reactants, which influences how easily they mix.

Reactants

________ are transformed into products in a chemical reaction by definition.

O3

Most collisions between NO and ________ molecules in the reaction vessel contain only enough energy for the molecules to bounce off one other without reacting.

Physical state

________ influences rate by determining how well reactants can mix.

Humans age

________ over decades, and coal is formed from dead plants over hundreds of millions of years.

Temperature

________ influences reaction rate by increasing collision frequency and, more crucially, collision energy: The frequency with which collisions occur.

influences rate

Concentration ________ by influencing the frequency and, more importantly, the energy of collisions between reactant molecules.

response rate

Knowing the ________ is important because how quickly a drug acts may mean the difference between life and death, and how long it takes a commercial product to develop can be the difference between profit and loss.

Chemical kinetics

________, the study of how quickly change happens, focuses on the reaction rate, or the change in reactant (or product) concentrations as a function of time.

Physical state

________: In order for molecules to collide, they must first mix.

influences rate

Temperature ________ by influencing the frequency and, more importantly, the energy of collisions between reactant molecules.
