give reason respiration is considered as an exothermic reaction

✴⚫☛✔⛤Respiration is considered as an exothermic REACTION During respiration, glucose molecules are converted to other molecules in a series of steps. ... Respiration is considered to be an exothermic process because during the chemical reaction we call respiration, carbon dioxide and water is released as byproducts but most importantly, heat energy is also released✔⛤☚

✴⚫⛤☞✔In the process of digestion, food molecules get converted into simpler substances such as, glucose. Then glucose combine with oxygen and provide energy to our body. The whole process is known as respiration. As because, energy is released during the process of respiration, so it is considered an exothermic reaction.

✔glucose molecules are converted to other molecules in a series of steps.
They finally end up as carbon dioxide and water.
The reaction is
C6H12O6+6O2→6CO2+6H2O+2805 kJ
The reaction is exothermic because the C=Oand O-H bonds in the products are so much more stable than the bonds in the reactants.
BOND ENERGY is the average energy needed to break a bond.
Some bond energies are:
C-C = 347 kJ/mol
We can view the process as breaking all the bonds in the reactants to separate the atoms and then re-combining the atoms to form the bonds in the products.Almost 75 % of the energy released comes from formation of the stable C=O bonds in CO2.

Answer 2

Hey mate
here's is ur answer _____________________

______________________________________
Respiration considered as an exothermic reaction becoz During respiration, oxidation of glucose take place which produces a large amount of heat energy.


Equation:'--.


C6H12O6+ 6O2 >>>>>> 6H2O + 6CO2 + Energy.


dear:) hope its helps ☺
