Gen Chem II - Lec 15 - Reaction Mechanisms
Channel: Jeffrey A Tibbitt
Date: 2017-05-29

In this lecture we discuss multistep reaction mechanisms.  Cases where the initial step is slow and fast are both discussed with examples.  We see how to determine the differential rate law from a knowledge of the mechanism.  This is to be compared with determining the differential rate law from experimental data.  The rate-determining-step is visualized by an analogy of workers carrying boxes. 

The last slide discusses how enzymes provide an alternative reaction mechanism, which greatly speeds up reactions within the cell.  We use the hydrolysis of sucrose into glucose and fructose by the enzyme sucrase as an example.

Our lab helper, Dr. Claw, makes his first appearance.

General Chemistry II - Lecture 15 - Reaction Mechanisms

These videos are being made because I love teaching general chemistry.  Also, I want to provide clear videos that are captioned for the deaf and hard-of-hearing, as well as for international students who use English as a second language (ESL).  These video lectures are being used to assess such students as well as hearing students. However, any student of general chemistry should find the lectures very useful.  Clear and concise explanations, colorful notes, and simple diagrams are used.  All videos are uploaded under the Creative Commons license, so please feel free to use them in any way you.

These videos are hard work on my part, and I enjoy making them.  If you continue to watch, then you will not only learn chemistry, but also some interesting things about the state of Hawai'i.  Each video normally begins with a short clip taken on location, from somewhere in the Hawaiian Islands.  And if you are on the island of Maui or happen to visit, then please feel free to stop by the college and say hello.  
Enjoy and Aloha !!!
