What This Document Is
These are lecture notes from Principles of Chemical Science (5.111) at MIT, specifically from Lecture 26 on November 14, 2018. The core focus is the Nernst Equation and an introduction to the fascinating world of transition metals, with a compelling case study featuring cisplatin, an important anti-cancer drug. The notes bridge concepts of electrochemistry and coordination chemistry.
Why This Document Matters
These notes are essential for students enrolled in 5.111 seeking to understand the relationship between thermodynamics and electrochemical cell potential. They are particularly valuable when studying redox reactions, equilibrium, and the behavior of transition metal complexes. Understanding these concepts is foundational for further study in chemistry, biology, and materials science. The inclusion of cisplatin highlights the real-world applications of these principles in medicine.
Common Limitations or Challenges
This document provides a snapshot of a single lecture. It does not offer a comprehensive treatment of electrochemistry or transition metal chemistry. It assumes prior knowledge of redox reactions, Gibbs free energy, and basic chemical equilibrium. It’s a record *of* learning, not a substitute *for* learning. It will not solve problems for you, nor will it replace textbook readings or problem sets.
What This Document Provides
The full document includes: a review of reduction half-reactions and standard reduction potentials; a detailed explanation of the Nernst Equation and its application to calculating cell potential under non-standard conditions; an introduction to coordination complexes, including coordination number and notation; a discussion of coordination complex isomers (cisplatin and transplatin are visually presented); an explanation of the chelate effect; and reading assignments for continued study. It also includes an example problem demonstrating the application of the Nernst equation. This preview only provides a high-level overview of these topics.
