AIIMS 2018 Chemistry Entropy MCQ Question

The equation presented demonstrates that for a spontaneous process, the total entropy change of the universe (ΔS_universe) is positive, indicating that the entropy of the universe continuously increases. This aligns with the second law of thermodynamics, which states that in an isolated system, the total entropy can only increase or remain constant. The other options are not relevant as they do not provide any alternative explanations or correct interpretations of the entropy changes involved in spontaneous processes. Understanding this concept is crucial for grasping the thermodynamic principles governing chemical reactions and physical processes.
