In an isolated system, all of the following are true of the second law of thermodynamics EXCEPT
A) there is a natural tendency toward greater disorder in the organization of matter (increase in entropy).
B) the amount of useful energy decreases.
C) reactions cause energy to be converted from more useful to less useful forms.
D) all chemical reactions release more energy than they consume.

Question

Quizplus · Accepted Answer

The second law of thermodynamics states that the total entropy of an isolated system can never decrease over time, and is constant if and only if all processes are reversible. It does not state that all chemical reactions release more energy than they consume; this is incorrect because some reactions are endothermic, absorbing energy from their surroundings.
