Which is necessary for a process to be spontaneous? A) ΔH_sys< 0 B) ΔS_sys> 0 C) ΔS_surr< 0 D) ΔS_univ> 0 E) ΔG_sys= 0

Quizplus · Accepted Answer

For a process to be spontaneous, the entropy of the universe must increase (ΔS_univ > 0) which is represented by the equation ΔS_univ = ΔS_sys + ΔS_surr > 0. Therefore, the correct answer is D, where ΔS_univ = ΔS_univ > 0.
