Question

What is exothermic reaction. Explain in detail with examples.

Answer 1

Endothermic Reaction – An endothermic reaction is the opposite of an exothermic reaction. Heat is absorbed in an endothermic reaction. In an exothermic reaction, the enthalpy change has a positive value: ΔH > 0

Exothermic reactions may be written as chemical reactions. Exothermic processes may be written in reaction format, but are more general and often include a combination of chemical reactions or involve nuclear reactions. Here are examples of exothermic reactions and processes:

Examples of Exothermic Reactions

any combustion reactiona neutralization reactionrusting of iron (rust steel wool with vinegar)the thermite reaction

Answer 2

The process in which heat energy is liberated out is called exothermic reaction. for example
C+O2=CO2+heat
