Question

Define define exothermic and endothermic reaction give one example each of the chemical equation

Answer 1

Answer:

exotherimic reaction in which reaction evolution of heat and endothermic reaction in which reaction absorption of heat

Answer 2

1. Exothermic reactions:

Those chemical reactions during which heat is released are known as exothermic chemical reactions.

E.g.: Burning of fuels and respiration are examples of exothermic reactions.

2. Endothermic reactions:

Those chemical reactions during which heat is absorbed are known as endothermic reactions.

E.g.: Reaction between nitrogen and oxygen that results in nitric oxide is an example of an endothermic reaction.
