Updated: Average bond enthalpies

We’ve used calorimetry and Hess’s law to find enthalpies for a whole range of reactions.  We now move onto to using average bond enthalpies to find enthalpies for reactions.

The worksheet we will work on is here:-

• Hess’s law 3: bond energies
• Here is some of the work carried out in class, so far, on these

Please watch the video here to help you with those questions.  All classes will work on them during Friday’s lesson so watch before then (it’s less than 10 minutes!
