Question

Which value best determines whether a reaction is spontaneous?

A) change in Gibbs free energy, $\Delta G$

B) change in entropy, $\Delta S$

C) change in kinetic energy, $\Delta KE$

D) change in enthalpy, $\Delta H$

E) change in heat of formation, $\Delta H_0f$

Answer

Correct option is A) change in Gibbs free energy, $\Delta G$

Reaction is spontaneous if $\Delta G < 0$, and is not spontaneous if $\Delta G > 0$.
