Any spontaneous process in a system at constant T and p must decrease the Gibbs free energy (if the system is away from equilibrium) or leave the Gibbs free energy unchanged (if the system is at equilibrium).

Negative, the process is spontaneous and may proceed in the forward direction as written.
Positive, the process is non-spontaneous as written, but it may proceed spontaneously in the reverse direction.
Zero, the process is at equilibrium, with no net change taking place over time.
