Tentative course schedule - CH112 Lecture - Spring 2021

You will get the most of lectures if you have done the appropriate preparation beforehand. In this course, the preparation ahead of lecture will include:

  • Working through the material from the previous class by doing the assigned problems, and
  • Reading ahead the topics to be discussed (listed below) and working through the in-text Worked Example problems.
  • Doing assigned Top Hat problems based on these readings

The detailed laboratory schedule is provided in the separate lab syllabus.

Suggested assigned homework problems from Oxtoby (some of which will be used in crafting exams) are posted here. Please note: working through more than these problems is the best thing to do - the more practice you get, the better off you'll be!
