Question

Quizplus · Accepted Answer

The thermodynamic condition for a spontaneous process at constant temperature and pressure is that ΔG (the change in free energy) is negative. This means that the reaction is energetically favorable and will proceed spontaneously without the need for external energy input. Choices A and B refer only to the change in entropy, which may or may not be indicative of spontaneity. Choice D is incorrect because a positive ΔG indicates a non-spontaneous process, while choice E refers to standard conditions and may not be relevant to the specific conditions of the reaction.
