what is the difference between exothermic and endothermic reaction?

Question

Answer

Exothermic reaction is the reaction in which heat is produced.it means your solution will be heated.endothermic reaction is the reaction in which heat it used .it means your solution will become cold

Answer

Exothermic reaction - the reaction in which heat is evolved.Endothermic reaction - the reaction in which heat is required or the heat is given to the reaction.

Answer

Difference between Exothermic and Endothermic Reactions

Exothermic and endothermic reactions are two types of chemical reactions that differ in terms of energy exchange. These reactions play a crucial role in various natural and industrial processes. Let's delve into the details of each type and explore their differences.

Exothermic Reactions:
Exothermic reactions are chemical reactions that release energy in the form of heat, light, or sound. In these reactions, the reactants possess a higher amount of energy compared to the products. The excess energy is released into the surroundings, resulting in an increase in the temperature of the surrounding environment.

Key points about exothermic reactions:
1. Energy release: Exothermic reactions release energy in the form of heat, light, or sound.
2. Temperature change: The temperature of the surrounding environment increases.
3. Energy transfer: Energy flows from the system (reactants) to the surroundings.
4. Examples: Combustion reactions, such as burning wood or fuel, are classic examples of exothermic reactions.

Endothermic Reactions:
Endothermic reactions are chemical reactions that absorb energy from the surroundings to proceed. In these reactions, the reactants have a lower amount of energy compared to the products, and the energy required for the reaction is obtained from the surrounding environment.

Key points about endothermic reactions:
1. Energy absorption: Endothermic reactions absorb energy from the surroundings.
2. Temperature change: The temperature of the surrounding environment decreases.
3. Energy transfer: Energy flows from the surroundings to the system (reactants).
4. Examples: Photosynthesis, the reaction that occurs in plants to convert sunlight into chemical energy, is an example of an endothermic reaction.

Differences between Exothermic and Endothermic Reactions:
1. Energy exchange: Exothermic reactions release energy, while endothermic reactions absorb energy.
2. Temperature change: Exothermic reactions cause an increase in temperature, whereas endothermic reactions result in a decrease in temperature.
3. Energy transfer direction: Exothermic reactions transfer energy from the system to the surroundings, while endothermic reactions transfer energy from the surroundings to the system.
4. Examples: Exothermic reactions include combustion, while endothermic reactions include photosynthesis.

In conclusion, the key difference between exothermic and endothermic reactions lies in the energy exchange and temperature change. Exothermic reactions release energy and increase the temperature, while endothermic reactions absorb energy and decrease the temperature. These reactions have diverse applications and play a vital role in various natural and industrial processes.
