Question

what is an exothermic reaction? Why is respiration considered an exothermic reaction? Explain​

Answer 1

Answer:

It is a reaction in which heat is released along with formation of products in respiration we produce co2 and exhale and water and energy is also formed

Answer 2

Answer:

The reaction in which heat is evolved during the process is known as exothermic reaction.

During respiration, we inhale O2 which breaks the Carbohydrates (glucose) present in our food.

This combines and give CO2 and H2O along with Energy. That is why respiration is considered as an exothermic reaction.

$C6H12O6 + O_{2} --> 6CO_{2} + 12H_{2}O + Energy$
