CHAPTER 19 Chemical Kinetics

CHAPTER 19 Chemical Kinetics. Chemical Reactions There are two things that we are interested in concerning chemical reactions: 1) Where is the system going ( chemical equilibrium ). 2) How long will it take for the system to get to where it is going ( chemical kinetics ).

Rates and Rate Laws

Rates and Rate Laws. Reaction Rate. The change in concentration of a reactant or product per unit of time. Reaction Rates:. 2NO 2 (g) ? 2NO(g) + O 2 (g). 1. Can measure disappearance of reactants. 2. Can measure appearance of products. 3. Are proportional

The Collision Model

Temperature and Rate. The Collision Model Most reactions speed up as temperature increases. (E.g. food spoils when not refrigerated.) When two light sticks are placed in water: one at room temperature and one in ice, the one at room temperature is brighter than the one in ice.
