Exothermic and Endothermic Reactions Concept Map Explained
An exothermic and endothermic reactions concept map shows how chemical reactions transfer energy. Exothermic reactions release energy to the surroundings, usually as heat, so the temperature rises. Endothermic reactions absorb energy from the surroundings, so the temperature falls. The map links these two types to energy diagrams, enthalpy change and everyday examples.
- Energy transfer: heat released or absorbed by the system
- Enthalpy change: the sign of ΔH for each reaction type
- Energy profile diagrams: reactant and product energy levels compared
- Examples: combustion, neutralization, dissolving ammonium nitrate
- Activation energy: the energy barrier every reaction must overcome
Use the map to revise before a test, or to check that you can explain each branch in your own words. CogniGuide can build a personalized version from your own chemistry notes.

Exothermic and Endothermic Reactions FAQ
Common questions about energy changes in reactions, and how to build your own map.
What is the main difference between exothermic and endothermic reactions?
Exothermic reactions release energy to their surroundings, so the temperature of the surroundings rises. Endothermic reactions absorb energy from their surroundings, so the temperature falls.
Is burning fuel an exothermic or endothermic reaction?
Burning fuel is exothermic. It releases heat and light as the chemical bonds in the fuel and oxygen rearrange into carbon dioxide and water.
Which file types can I use to make my own reactions map?
You can upload PDF, Word (DOCX), PowerPoint (PPTX), text or Markdown files, or an image of your notes. You can also type the topic.
Can I turn my reactions map into a quiz for free?
Yes. The free plan includes 5 creations a week with no payment needed, and you can turn a map into a quiz to test yourself.
