Objectives Chapter 16
1.Discuss changes in enthalpy (read a graph).
2. Relate enthalpy changes to amounts of reactant or product.
3.Discuss enthalpy and reaction tendency.
4.Define entropy (and list the symbol).
5.Discuss changes in entropy.
6. Discuss entropy and reaction tendency.
7. Discuss the collision theory.
8.Discuss activation energy and identify it on a graph.
9. When given a graph of reaction progress and energy determine ∆H and
the activation energy.
Objectives Chapter 17 Kinetics
1. Discuss the five factors that effect the rate of reaction.
Objectives Chapter 18 Equilbrium
1. Define chemical equilibrium.
2. Write the expression for chemical equilibrium.
3. Determine the value of the equilibrium constant.
4. Determine the concentration of speices when give Keq.
5.Predicts shifts in equilibrium according to Le Chatelier’s principle.
Objectives Chapter 19 Redox
1. Determine oxidation numbers for given elements, compounds, and ions.
2. Discuss the process of oxidation – reduction.
3. Determine whether a substance is oxidized or reduced.
4. Determine whether a chemical reaction is a redox reaction.
Objectives Chapter 22 Nuclear
1. Define mass defect, and nuclear reactions.
Mass defect- the difference bwtween the mass of an atom and the mass of
the sum of the protons and neutrons.
Example pg. 701. Please note..it is a very, very small number.
Nuclear reactions – reaction that changes the nucleus of an atom. In a
nuclear reaction the number of protons changes…so does the identity of
the element.
2. Complete and balance nuclear equations.
Pg 704
4. Define half life.
Half life (t1/2) is the time that it takes for exactly half of the atoms of a
radioactive nuclide to decay.
5. Perform calculations with first order decay.
Perform step wise calculations.
