We’ll talk more about what happens to the temperature during a reaction in the next section. In Chemistry, there are a lot of chemical reactions, which are broken up into many smaller and larger reactions. There are two kinds of reactions, depending on what happens to the temperature. These are both exothermic and endothermic reactions. Here we have explained the difference between endothermic and exothermic reactions.
What Are the Difference Between Endothermic and Exothermic Reaction
- Exothermic Reaction: Chemical processes that release energy from heat, light, or sound are exothermic. Typically, this energy is released when the chemical bonds in the reactants are shattered, and new bonds are generated in the products.
- Endothermic reactions: however, are chemical reactions that absorb energy. Typically, this energy is absorbed when chemical bonds in the reactants are broken, and new bonds are generated in the products. Endothermic reactions include photosynthesis, the mechanism by which plants transform light energy into chemical energy, and the production of chemicals such as ammonium nitrate (NH4NO3).
- In endothermic reactions, the enthalpy of the reactants is smaller than the enthalpy of the products.
- In exothermic processes, the enthalpy of the reactants is greater than that of the products.
- Endothermic reactions, which are those that contribute energy to the system, are desirable.
- Endothermic reactions discharge energy from the system.
- For endothermic processes, the enthalpy change (ΔH) is positive.
- For exothermic reactions, the change in enthalpy (ΔH) is negative.
- Endothermic Reactions: Photosynthesis, Evaporation, Cooking an egg
- Exothermic Reactions: Formation of rain, Concrete, Combustion
- Endothermic Reactions: The temperature of the surrounding is decreased
- Exothermic Reactions: The temperature of the surrounding is increased
Is Melting Endothermic or Exothermic?
Melting is endothermic, which means it absorbs heat from its surroundings. The melting point of a substance determines the precise amount of heat required to melt it. The melting process occurs when a substance transitions from a solid to a liquid condition.
In conclusion, exothermic reactions are chemical reactions that release energy through heat, light, or sound, whereas endothermic reactions are chemical reactions that absorb energy. The change in energy in a chemical process can be measured by calorimetry, and both exothermic and endothermic reactions have numerous commercial and everyday applications. Exothermic and endothermic reactions have several uses in numerous sectors, including the creation of heat and electricity, the manufacture of chemicals, the production of fuels, the metallurgy, the refrigeration process, and air conditioning systems. Knowing the distinction between exothermic and endothermic processes is vital for numerous businesses and the creation of innovative technology.
