In cases where ΔG is: 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.
U slučajevima gde je ΔG: negativno, proces je spontan i može da teče unapred kao što je napisano. positivno, proces is nespontan kako je napisan, ali on možda može da se spontano odvija u suprotnom smeru. nula, proces je u ravnoteži, i nema neto promena tokom vremena.
