Exothermic reactions are fascinating because they release energy in the form of heat. This energy release occurs when the bonds formed in the products are stronger than the bonds broken in the reactants.
The released energy is often visible or tangible, as it increases the temperature of the surroundings, including the reaction vessel itself. Just think of a reaction like combustion: when wood burns, it releases heat. That heat is what you feel when you're near a campfire, providing warmth.
- The energy of the reactants is greater than that of the products.
- Excess energy is dispersed into the environment as heat.
- This process makes the reaction vessel feel warm.
The reason you feel heat is due to the energy flow from the system (reaction) to the surroundings. As this heat disperses, our skin detects the temperature increase, explaining the warmth you encounter.
