Chemical and Physical Change: Energy, Rate, and Equilibrium
Chemical and Physical Change: Energy, Rate, and Equilibrium
Learning Goals
1. Correlate the terms endothermic and exothermic with heat flow between a system and its surroundings.
2. State the meaning of the terms enthalpy, entropy, and free energy and know their implications.
3. Describe experiments that yield thermochemical information and calculate fuel values based on experimental data.
4. Describe the concept of reaction rate and the role of kinetics in chemical and physical change.
5. Describe the importance of activation energy and the activated complex in determining reaction rate.
6. Predict the way reactant structure, concentration, temperature, and catalysis affect the rate of a chemical reaction.
7. Write rate equations for elementary processes.
8. Recognize and describe equilibrium situations.
9. Write equilibrium-constant expressions and use these expressions to calculate equilibrium constants.
10. Use LeChatelier's principle to predict changes in equilibrium position.
