SUMMARY
Adsorption, coagulation, and flocculation are critical processes for the removal of target substances from mixtures, demonstrating a spontaneous decrease in entropy. This observation raises questions about the applicability of the second law of thermodynamics in these contexts. The discussion emphasizes the relationship between these processes and thermodynamic principles, particularly through the equation dH - TdS ≤ 0, which highlights the importance of considering the entire system's entropy. Understanding these concepts is essential for grasping the complexities of thermodynamic behavior in chemical processes.
