The main difference between Exothermic Reaction and Endothermic Reaction: Exothermic and endothermic reactions represent two energy dynamics in chemical processes, essential for CBSE Class 10 Chemistry. Understanding their differ
Exothermic Reaction vs Endothermic Reaction — Comparison Table
| Basis | Exothermic Reaction | Endothermic Reaction |
|---|---|---|
| Energy transfer | Releases heat to surroundings | Absorbs heat from surroundings |
| Temperature change | Surroundings become hotter | Surroundings become cooler |
| Activation energy | Less than energy released | Greater than energy released |
| Examples | Burning, neutralization, rusting | Melting ice, evaporation, photosynthesis |
| ΔH (enthalpy) | Negative (ΔH < 0) | Positive (ΔH > 0) |
Key Points
- Exothermic releases energy (heat, light); endothermic absorbs energy
- Most combustion reactions are exothermic
- Ice melting is endothermic; steam condensing is exothermic
- Energy diagram shows activation energy and heat released or absorbed
