Gibbs free energy can best be defined as the
A) difference between the enthalpy and entropy of a system at a given temperature.
B) difference between exothermic and endothermic energy of a system at a given temperature.
C) addition of enthalpy and entropy of a system at a given temperature.
D) difference between pressure and volume at a given temperature.

Question

Quizplus · Accepted Answer

Gibbs free energy is defined as the difference between the enthalpy and entropy of a system at a given temperature. It represents the maximum amount of work that can be obtained from a system at constant temperature and pressure. Option B is incorrect because exothermic and endothermic energy are not directly related to Gibbs free energy. Option C is incorrect because the addition of enthalpy and entropy does not account for the spontaneity of a reaction or process. Option D is incorrect because pressure and volume are not directly related to Gibbs free energy.
