Objectives

You have completed this lesson when you can:

1. Describe the process of a chemical reaction, including the making and breaking of bonds and the energy absorbed/released in doing so, using collision theory.

2. Draw, label, and interpret a reaction coordinate diagram that includes the following elements:

• Activation Energy

• Reaction Enthalpy

• Transition State/Activated Complex

• Thermicity (exo/endo)

3. Perform calculations involving the enthalpy change of a reaction (ΔH).

4. Describe how and why the rate of a reaction is affected by:

• Temperature

• Reactant concentration

• Reactant surface area

• Catalysts

5. Explain the features of a dynamic chemical equilibrium, including how forward and reverse reactions in a reversible process lead to dynamic equilibria and what it means for an equilibrium to be dynamic.

6. Use Le Chatelier's principle to explain and predict how chemical equilibria respond to disruptions in:

• Reactant and product concentration

• Temperature

• Pressure

7. Given the equation for a reversible chemical reaction, write an expression for the reaction's equilibrium constant (K)

8. Calculate the value of an equilibrium constant given reactant and product concentrations at equilibrium.

9. Calculate a reactant or product concentration at equilibrium given the value of K and other reactant/product concentrations.
