Discontinuous reactions in solids
WebJan 25, 2024 · The second law of thermodynamics states that a spontaneous process increases the entropy of the universe, Suniv > 0. If Δ Suniv < 0, the process is nonspontaneous, and if Δ Suniv = 0, the system is at equilibrium. The third law of thermodynamics establishes the zero for entropy as that of a perfect, pure crystalline … WebThe amount of liquid decreases as the temperature drops until all of the liquid is used up in producing solids.
