Exothermic and endothermic reactions
These diagnostic questions and response activities (contained in the zip file) support students in being able to:
- Recognise that energy is conserved during an exothermic reaction.
- Describe how the temperature of the chemicals will change with time after an exothermic reaction.
- Describe how the temperature of the chemicals will change with time after an endothermic reaction.
- Explain the energy changes needed for the rearrangement (breaking apart and combining) of atoms during a chemical reaction.
- Recognise that the overall energy change of a chemical reaction depends on the relative amount of energy needed to separate and combine atoms during the reaction.
The resources include details of common misconceptions and a summary of the research upon which the resources are based.
