Question

the chemical equation for burning paper, or cellulose, is c₆h₁₀o₅ + 6o₂ → 6co₂ + 5h₂o. compare the potential energy stored in the bonds of the reactants to the potential energy stored in the bonds of the products. provide an explanation as to why there is more energy stored in one set of bonds than the other.

Explanation:

Step1: Understand exothermic reactions

Burning paper is an exothermic reaction. In exothermic reactions, energy is released.

Step2: Compare bond - energy

The reactants ($C_6H_{10}O_5$ and $O_2$) have more potential energy stored in their bonds than the products ($CO_2$ and $H_2O$). This is because when the reaction occurs, energy is released as the more stable products are formed. The products have stronger and more stable bonds. For example, the double - bonds in $CO_2$ and the $O - H$ bonds in $H_2O$ are very stable. The difference in the potential energy of the bonds of reactants and products is released as heat and light during the burning process.

Answer:

The reactants ($C_6H_{10}O_5$ and $O_2$) have more potential energy stored in their bonds than the products ($CO_2$ and $H_2O$) because the reaction is exothermic and the products have more stable bonds.
