Question

\[\ce{C6H12O6_{(aq)} + 6O2_{(g)} -> 6CO2_{(g)} + 6H2O_{(l)}}\]

The above reaction is an example of ______.

Options

• Displacement Reaction

• Endothermic Reaction

• Exothermic Reaction

• Neutralisation Reaction

Answer 1

\[\ce{C6H12O6_{(aq)} + 6O2_{(g)} -> 6CO2_{(g)} + 6H2O_{(l)}}\]

The above reaction is an example of exothermic reaction.

Explanation:

The given reaction, \[\ce{C6H12O6_{(aq)} + 6O2_{(g)} -> 6CO2_{(g)} + 6H2O_{(l)}}\] is the equation for cellular respiration (the oxidation of glucose), which releases energy (as ATP and heat) while breaking down glucose in the presence of oxygen. Because it releases energy rather than absorbing it, it is classified as an exothermic reaction
