What are Exothermic Reactions? (with Examples and Video) - BYJU

WebAn exothermic reaction is a reaction in which energy is released in the form of light or heat. Thus in an exothermic reaction, energy is transferred into the surroundings rather than taking energy from the surroundings as in an endothermic reaction. In an exothermic reaction, the change in enthalpy ( ΔH) will be negative. WebExothermic: Bond-breaking is said to be endothermic because energy is consumed to create bonds and released when bonds are broken. And the process of bond … WebBond energy – a measure of bond strength; determined by measuring the enthalpy or energy required to break a molecule.
