Re: Spontaneity
Gibbs free energy can be used to determine the "spontaneity" of a reaction due to the fact Gibbs free energy change is the total energy change of the system.

Re: Spontaneity
△G determines whether a reaction can happen spontaneously. Negative △G is spontaneous, and positive △G is not. It is also related to which way of reaction can be more stable. The lower △G is, the more stable it is.

Re: Spontaneity
When change in Gibbs free energy is negative, the reaction is spontaneous; when delta G is positive, the reaction is not spontaneous.
Re: Spontaneity
If Gibbs is at 0 it is at equilibrium, if it is negative then it is exergonic meaning it is also spontaneous. If it is positive it is endergonic which means it is non-spontaneous. The lower the delta G is the more stable it is.
