Question

Quizplus · Accepted Answer

The correct statement of a law of thermodynamics is that every spontaneous process is accompanied by an increase in total entropy. This is stated in the second law of thermodynamics. Choice A is incorrect because the enthalpy of the universe can neither be created nor destroyed, but it can be transferred or converted from one form to another. Choice B is incorrect because the entropy of the universe is constantly increasing. Choice C is incorrect because the entropy of an element in its standard state at 25°C is not necessarily zero. Choice E is incorrect because every spontaneous process is accompanied by a decrease in the free energy of the system, not the enthalpy.
