Review 18
1. Understand Chemical equilibrium- all graphs
-dynamic, reversible
2. Equilibrium Constant expressions
3. What does K mean? if it is large? if it is small? if it is equal to 1
4. Solve p. 559, 1-4
5. LeChatelier's principle- Pressure, Concentration, Temperature
Describe equilibrium shifts in a chemical system caused by changing conditions (Le Chatelier’s
Principle).
Predict shifts in a chemical system caused by changing conditions (Le Chatelier’s Principle).
Predict the extent reactants are converted to products using the value of the equilibrium constant.
