The vaporization of a liquid at a certain temperature and pressure is spontaneous. For this process, which of the inequalities regarding the Gibbs free energy G and the internal energy E are correct? 1. AG 〈 0 (A) I only (C) Both I and II (B) II only (D) Neither I nor II

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.
