Which of the following statements is true?

Question

Quizplus · Accepted Answer

Spontaneity can depend on the temperature. This is because the Gibbs free energy change (ΔG) of a reaction determines its spontaneity, and ΔG is dependent on both the enthalpy (ΔH) and entropy (ΔS) of the system, which can both vary with temperature. Therefore, the spontaneity of a process may change as the temperature changes. Choices A, B, and D are incorrect because processes that are spontaneous in one direction are not necessarily spontaneous in the opposite direction, processes can be spontaneous even if they occur at an unobservable rate, and not all of the statements are true.
