The enthalpy of combustion of glucose is -2808 kJ mol-1. Which one of ...
A system with lower energy is more stable than a system with higher energy. If the enthalpy change for a reaction (such as the combustion of glucose) is negative, then energy must be released by the system during the reaction such that the system has lower energy after the reaction than before. In this case, the products of the combustion of glucose must be more stable than glucose itself.

Enthalpy of Combustion of Glucose
Introduction:
The enthalpy of combustion is the amount of heat energy released or absorbed during a combustion reaction. Glucose is a carbohydrate that can undergo combustion to produce carbon dioxide and water. The enthalpy of combustion of glucose is a measure of the heat energy released when one mole of glucose reacts with oxygen to form carbon dioxide and water.
Statement:
The false statement regarding the enthalpy of combustion of glucose is option A, which states that the products of the combustion of glucose are less stable than glucose itself.
Explanation:
To understand why option A is false, we need to consider the concept of stability in relation to chemical reactions.
Stability of Reactants and Products:
In a chemical reaction, the reactants are transformed into products. The stability of a substance refers to its tendency to remain unchanged under specific conditions. More stable substances have lower energy levels and are less likely to undergo further reactions.
Combustion of Glucose:
When glucose undergoes combustion, it reacts with oxygen to form carbon dioxide and water. The combustion of glucose is a highly exothermic process, meaning it releases heat energy. This indicates that the products of the combustion reaction are more stable than the reactant, glucose.
Exothermic Process:
Option B states that the combustion of glucose is exothermic, which is true. In an exothermic reaction, the products have lower energy content than the reactants. This release of energy occurs in the form of heat.
Overall Energy Liberation:
Option C states that overall, energy is liberated when the combustion of glucose occurs. This is also true since the enthalpy of combustion for glucose is negative, indicating a release of heat energy.
Conclusion:
The false statement in this case is option A, which claims that the products of the combustion of glucose are less stable than glucose itself. In reality, the combustion of glucose produces more stable products, carbon dioxide and water, compared to the reactant glucose.
