Label activation energy on a reaction profile.

In the subtopic Reaction profiles, this learning objective focuses on label activation energy on a reaction profile. It belongs to Exothermic and endothermic reactions in AQA GCSE Chemistry 8462 Unit 4.5 Energy changes, so the explanation must stay inside energy-transfer, reaction-profile, cell, fuel-cell, exothermic, endothermic, activation-energy or bond-energy context as appropriate. Approved keywords to use include reaction profile, activation energy. Activation energy. means the minimum energy particles need to react Avoid the mistake of students often confuse activation energy with the overall energy change of the reaction, thinking they are the same; instead, remember that activation energy is the minimum energy required for reactants to collide and react, while the overall energy change refers to the difference in energy between reactants and products For exam answers, when studying reaction profiles, always label the activation energy clearly to show the minimum energy required for the reaction to occur
