Unit 8, Quiz #1
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 ...
- 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.
Chapter 17.1-2; Chapter
17.1-2 Reading Guide (pp. 1-2); Lab KE1; Class notes on collision model
- 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)
- 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)
- Equilibrium Concept: To understand the concept of reversible reaction systems and the characteristics of dynamic equilibrium.
Chapter 17.3-4; Chapter 17.3-4 Reading Guide (pp. 11-12); Lab KE3
- 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.

Constant Expressions (pp. 13-16), Equilibrium Position (pp. 17-18);
Equilibrium Calculations (pp. 19-20)
- 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.
