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.
