Energy Changes and Rates of Reaction
Lesson 5: Bond Energies
Primary Learning Goal
I can use average bond energies to estimate the enthalpy change for a chemical reaction.
Work
1. Read section 5.3.
!!! STOP reading at the bottom of page 308. Use the example calculations presented in the video lesson and summary as a guide, NOT the examples given on pages 309 to 312.
2. Watch the video lesson (27 min) and take notes. You can find a table of average bond energies in your information package.
3. Check out this summary and example calculation.
4. Do questions 1ab, 2a, 3 on page 313 (Note: HCN has a triple bond between C and N).
5. Check your solutions and review as necessary.
6. Go to Edsby and complete Energy and Rates Lesson-5 Quiz.
