The concept of free energy allows prediction of spontaneity of a process by considering the changes in ________ and ________ during the process.

Question

Quizplus · Accepted Answer

The concept of free energy (ΔG) takes into account both changes in enthalpy (ΔH) and entropy (ΔS) during a process. The equation for ΔG is ΔG = ΔH - TΔS, where T is the temperature in Kelvin. Therefore, the correct options are those that involve enthalpy and entropy. Choices B, C, and E are incorrect because they include mass or temperature, which are not directly related to the spontaneity of a process.
