What This Document Is
This document is a recitation assignment for Drexel University’s CHEM 102 (General Chemistry II) course, specifically for Week Four of the Winter 2021 term. It presents a series of problems focused on chemical equilibrium, building upon concepts introduced in Chapter 15 (and referencing Chapter 22). Students are tasked with identifying relevant key concepts and equations from the textbook to approach each problem. The assignment emphasizes preparation for in-class discussion, but does *not* require fully solved answers.
Why This Document Matters
This recitation assignment is crucial for students in CHEM 102 as it reinforces their understanding of equilibrium principles. It bridges the gap between theoretical knowledge from lectures and the practical application of those concepts to problem-solving. Completing this assignment prepares students to actively participate in recitation, demonstrating their grasp of the material and identifying areas where they need further clarification. It’s designed to be completed *before* class, serving as a focused review and preparation tool.
Common Limitations or Challenges
This document is not a comprehensive lesson or a solution manual. It provides problems to work through, but doesn’t offer step-by-step guidance on *how* to solve them. Students are expected to have a foundational understanding of equilibrium constants, Le Chatelier’s principle, and related concepts from the textbook and lectures. It also doesn’t cover all possible equilibrium scenarios; it’s a targeted practice set.
What This Document Provides
The full document includes:
* Equilibrium constant expression correction problems.
* Exercises requiring the writing of equilibrium constant expressions for given reactions.
* Calculations involving equilibrium constants (K) and equilibrium concentrations.
* Application of Le Chatelier’s principle to predict the effect of disturbances on equilibrium.
* Problems involving the relationship between equilibrium constants for coupled reactions.
* A conceptual question regarding the impact of volume on equilibrium.
* Additional, more challenging problems designated for Honors students.
This preview does *not* include solutions to the problems, detailed explanations of the concepts, or worked examples. It only describes the types of problems included in the full assignment.
