Koch · Answer 1

1, ΔG<0

Explanation:

Gibbs free energy is used to describe the reaction, wether it is spontaneous, not spontaneous or at equilibrium. If it is spontaneous, ΔG0, and if it is at equilibrium, ΔG=0.

Therefore, because the said vaporization is a spontaneous process, the correct answer is under 1.
