Create and interpret potential energy diagrams, for example: chemical<br />
reactions, orbits around a central body, motion of a pendulum<br />
Students will participate in activities (Pasco) to create exothermic and<br />
endothermic graphs.<br />
Students will be able to interpret exothermic and endothermic reaction graphs.<br />

Thermochemical equations<br />
Chapter 18 Reaction Rates and Equilibrium<br />
The student will learn how the rate of a chemical reaction can<br />
be controlled, what the role of energy is and why some<br />
reactions occur naturally and others do not.<br />
Explain how various factors, such as concentration, temperature, and<br />
presence of a catalyst affect the rate of a chemical reaction.<br />
Students will be able to describe how each factor may affect the rate of a<br />
chemical reaction.<br />
Students will be able to compare the relative effect of each factor on the rate of a<br />
chemical reaction.<br />

Explain the concept of dynamic equilibrium in terms of reversible processes<br />
occurring at the same rates.<br />
Students will be able to describe a system in dynamic equilibrium.<br />
Students will be able to describe how factors may affect the equilibrium of a<br />
reaction.<br />

Le Chatelier principle<br />
Explain entropy’s role in determining the efficiency of processes that convert<br />
energy to work.<br />
Students will be able to describe the change in entropy of a reaction.<br />
Students will be able to determine if a reaction is spontaneous<br />
