If a certain process has ΔS_univ 0 at 25°C, the process may be described as A) exothermic. B) endothermic. C) spontaneous. D) moving rapidly toward equilibrium. E) violating the second law of thermodynamics.

Question

If a certain process has ΔS_univ> 0 at 25°C, the process may be described as A) exothermic. B) endothermic. C) spontaneous. D) moving rapidly toward equilibrium. E) violating the second law of thermodynamics.

Quizplus · Accepted Answer

A process with ΔS_univ > 0 at any temperature, including 25°C, is considered spontaneous according to the second law of thermodynamics. This law states that for a process to be spontaneous, the entropy of the universe (system plus surroundings) must increase.
