AQA Working out bond energies for Exothermic and Endothermic reactions

This resource is good for GCSE AQA Chemistry on working out whether a reaction is endothermic or exothermic based on the bond energies. It would also work with a high ability year 8 group following the Kerboodle Activate scheme of work.

Powerpoint takes you through key idea of endothermic and exothermic again, then has some worked examples of how to work out the bond energies.

Worksheet tests students knowledge starting with easy pre-balanced equations and ending with combustion of alkanes to be worked out from scratch .
