exothermic reaction

Let us learn about exothermic reaction

An exothermic reaction is referred as a chemical reaction which releases energy in the form of heat. Exothermic reaction is the opposite of an endothermic reaction. The chemical reaction in that heat is evolved is known as exothermic reaction.

Many chemical reactions release energy in the form of light, heat, or sound. These are called as exothermic reactions. Exothermic reactions may generate spontaneously & result in higher randomness or entropy (ΔS > 0) of the system. Exothermic reaction is denoted by a negative heat flow & decrease in enthalpy (ΔH <>

Bond breaking always needs energy while bond making always release energy. The balance between 2 processes result in 2 types of reactions exothermic & endothermic reaction. When the energy generated by bond forming is greater than the energy consumed by bond breaking there is a net generate of chemical energy. This type of reaction is known exothermic reaction.


In our next blog we shall learn about integral calculator step by step I hope the above explanation was useful.Keep reading and leave your comments.

  1. Very nice information for Exothermic Welding System provide contact surface area is 100% not analogous to any chance of oxidation. The technology is mainly used in higher applications like rail tracks, etc.
