Final answer:
The correct answer is d) all of the above. In the given chemical reaction, glucose reacts with oxygen to form carbon dioxide and water, resulting in an increase in entropy, a negative change in enthalpy, and a negative change in Gibbs free energy.
Step-by-step explanation:
The correct answer is d) all of the above.
In the given chemical equation, Glucose + 6O2 → 6CO2 + 6H2O, all three statements are true.
a) Entropy increases: Entropy is a measure of the disorder or randomness in a system. In this reaction, the number of gas molecules increases from one glucose molecule and six oxygen molecules to six carbon dioxide molecules and six water molecules, leading to an increase in entropy.
b) Change in H < 0: The reaction is exothermic, meaning it releases energy in the form of heat. Since the change in enthalpy (H) is negative, it indicates a decrease in enthalpy.
c) Change in G0 < 0: The change in Gibbs free energy (delta G) in this reaction is negative, indicating that the reaction is spontaneous and favors the formation of products.
