ENDOTHERMIC REACTION Difference b/w Endothermic and Exothermic reaction
An endothermic reaction is one that requires or needs energy. This energy is supplied from the surroundings and the amount supplied can vary.
One of the most common examples of these reactions is photosynthesis, in which plants take energy from sunlight and then convert water and carbon dioxide into oxygen and sugar.
Symbolic equation: A + energy–> D
In this type of reaction, the energy content of the reactants is lower than that of the products.
Examples:
- Melting of ice.
- Dissolution of ammonium nitrate in water.
EXOTHERMIC REACTION
An exothermic reaction is just the opposite of the one previously described. In some types of exothermic processes, a certain amount of heat may initially be required to start the process. Once this is supplied, the system begins to produce heat on its own. All combustion reactions fall into this category.
Symbolic equation: A–> B + C + energy
In this case, the energy content of the products is higher than that of the reactants.
Examples:
- Digestion of food.
- All combustion reactions (fires).
- Adding an alkali metal to water.
Key differences between endothermic and exothermic reactions
- Endothermic reactions require energy, while exothermic reactions release it.
