Question

Quizplus · Accepted Answer

According to the Second Law of Thermodynamics, spontaneous processes always lead to an increase in entropy (disorder) of the system and its surroundings. Therefore, a reaction that is accompanied by an increase in entropy (i.e. more chaos) is more likely to be spontaneous. Additionally, a lowering of energy can also contribute to spontaneity, as the system prefers to be in a lower energy state. Thus, the best choice is B (lowering energy and increasing entropy).
