Question

What does one mean by exothermic and endothermic reactions? Give examples.​

Answer 1

Explanation:

The chemical reactions which occur with the evolution of heat are called exothermic reactions. For example, Heat Heat The chemical reactions which occur with the absorption of heat are called endothermic reactions.

Answer 2

reaction in which heat energy is liberated by the reactants is called exothermic reaction. eg: Carbon + Oxygen gives Carbon Dioxide + Q. reaction in which heat energy is absorbed by the reactants is called endothermic reaction. eg: Nitrogen + Oxygen gives 2 nitrous oxide (2NO) - Q
