Which of the following is the most spontaneous reaction? A reaction that is ________.

Question

Quizplus · Accepted Answer

Spontaneity in chemical reactions is often determined by the Gibbs free energy change ($\Delta G$), which is influenced by both enthalpy ($\Delta H$) and entropy ($\Delta S$) changes, as well as temperature. A reaction that is slightly exothermic ($\Delta H < 0$) and leads to a huge increase in entropy ($\Delta S > 0$) is more likely to be spontaneous under a wide range of temperatures, as both factors ($\Delta H$ and $\Delta S$) favor spontaneity according to the equation $\Delta G = \Delta H - T\Delta S$.
