Question
Which of the following is not an endothermic reaction?
Options
\[\ce{CaCO3 -> CaO + CO2}\]
\[\ce{2H2O -> 2H2 + O2}\]
\[\ce{6CO2 + 6H2O -> C6H12O6 + 6O2}\]
\[\ce{C6H12O6 + 6O2 -> 6CO2 + 6H2O}\]

Solution
\[\ce{C6H12O6 + 6O2 -> 6CO2 + 6H2O}\]
Explanation:
This equation represents cellular respiration, a vital process where glucose breaks down in the presence of oxygen to release energy for our bodies. Because it releases energy rather than absorbing it, it is highly exothermic.
