Unit 8, Quiz #1
2017-18



Your first quiz of Unit 6 will be on Monday, April 30 and cover material from Chapter 17 of the textbook. Quiz questions will target the following objectives.


You should be able to ...
  1. Reaction Rates:  To understand how the variables of concentration, temperature, catalysts, and surface area affect the rate of a reaction to explain such dependencies in terms of the Collision Model.

    Resources: Read Chapter 17.1-2;  Chapter 17.1-2 Reading Guide (pp. 1-2); Lab KE1; Class notes on collision model



  2. Method of Initial Rates:  To inspect a data set of concentration-rate data in order to determine the order of reaction, the rate law, and the rate constant.

    Resources: Reaction Rates (pp. 3-6)



  3. Reaction Mechanisms:  To understand the concept of a reaction mechanism and associated terms (catalyst, intermediate, molecularity, elementary steps, rate-determining steps) and to be able to evaluate the validity of a mechanism by relating the mechanism to an experimentally derived rate law and to the balanced chemical equation.

    Resources: Reaction Mechanisms (pp. 7-9)



  4. Equilibrium Concept:  To understand the concept of reversible reaction systems and the characteristics of dynamic equilibrium.

    Resources: Read Chapter 17.3-4; Chapter 17.3-4 Reading Guide (pp. 11-12); Lab KE3



  5. Equilibrium Constant and Calculations:  To write an equilibrium product expression (Kp or Kc) for any reaction system and use it to calculate K, to calculate equilibrium pressures and concentrations, to predict the direction a reaction system would proceed to reach equilibrium, and to combine their use with an ICE table to solve a complex problem.

    Resources: Read Chapter 17.3-4; Chapter 17.3-4 Reading Guide (pp. 11-12); Equilibrium Constant Expressions (pp. 13-16), Equilibrium Position (pp. 17-18); Equilibrium Calculations (pp. 19-20)



  6. LeChatelier's Principle:  To predict the direction that a reaction mechanism would shift in order to relieve the stress of an added or removed reactant or product, a change in container volume, or a change in temperature.

    Resources: Read Chapter 17.7; Chapter 17.7 Reading Guide (pp. 21-22); LeChatelier's Principle (pp. 23-24); Lab KE4
