The Gibbs free energy change of a reaction gives a measure of the energy from a reaction that is available to do something useful (that is, to do work) once some of the energy has been used to increase the entropy; it isn't the amount of energy that is used to increase the entropy, however.

Which of the following statements regarding the Gibbs free energy chan...
Explanation:
The Gibbs free energy change for a reaction is a measure of the spontaneity and feasibility of a reaction. It takes into account both the enthalpy change (ΔH) and the entropy change (ΔS) of the system.
a) The Gibbs free energy change is the proportion of the enthalpy change of a reaction that is used to increase the entropy
This statement is false. The Gibbs free energy change (ΔG) is not a proportion of the enthalpy change (ΔH) that is used to increase the entropy (ΔS). In fact, the Gibbs free energy change is given by the equation ΔG = ΔH - TΔS, where T represents the temperature in Kelvin. This equation shows that the Gibbs free energy change takes into account both the enthalpy change and the entropy change, but it does not imply that the enthalpy change is used to increase the entropy.
b) If the Gibbs free energy change for a reaction is negative, the reaction happens spontaneously
This statement is true. If the Gibbs free energy change (ΔG) for a reaction is negative, it means that the reaction is exergonic and happens spontaneously. A negative ΔG indicates that the reaction releases energy and is thermodynamically favorable.
c) The Gibbs free energy is represented by the symbol G
This statement is true. The Gibbs free energy is represented by the symbol G. It is a thermodynamic potential that measures the maximum reversible work that can be performed by a system at constant temperature and pressure.
d) A reaction with a negative Gibbs free energy change of reaction is called an exergonic reaction
This statement is true. A reaction with a negative Gibbs free energy change (ΔG) is called an exergonic reaction. It is a reaction that releases energy and is thermodynamically favorable.
In conclusion, the false statement is option 'A'. The Gibbs free energy change is not a proportion of the enthalpy change that is used to increase the entropy. Instead, it takes into account both the enthalpy change and the entropy change of a reaction.
