Question

explain exothermic reaction...​

Answer 1

Answer:

An exothermic reaction is a "reaction for which the overall standard enthalpy change ΔH⚬ is negative."[1][2] Exothermic reactions usually release heat and entail the replacement of weak bonds with stronger ones.[3][4] The term is often confused with exergonic reaction, which IUPAC defines as "... a reaction for which the overall standard Gibbs energy change ΔG⚬ is negative."[2] A strongly exothermic reaction will usually also be exergonic because ΔH⚬ makes a major contribution to ΔG⚬. Most of the spectacular chemical reactions that are demonstrated in classrooms are exothermic and exergonic. The opposite is an endothermic reaction, which usually takes up heat and is driven by an entropy increase in the system.

Answer 2

Answer:the reaction in which energy is released is called exothermic reaction

the reaction in which ebergy is absorbed is called endothermic reaction

hope this helps
