Spontaneity

[Jesse_torres2H]

What value indicates spontaneity is it a positive or negative delta g

[Christy Lee 2H]

Negative delta G is spontaneous because free energy goes from a higher energy state to a lower energy state which is favorable.

[Ivy Lu 1C]

A negative delta G is spontaneous because there is a lost in free energy, and going from high free energy to low free energy is favorable. A positive delta G is nonspontaneous because there is a gain in free energy. For that to happen, energy would have to be added, making the reaction nonspontaneous.

[Amanda Wu 2C]

A negative delta G indicates that a reaction/process is spontaneous or favorable. This is due to the fact that a negative delta G indicates a loss of free energy (going from a higher free energy of the reactants to a lower free energy of the products), which is a favorable process.

[Abby Ellstrom 1I]

Negative delta G signifies spontaneity while positive delta G reactions are not spontaneous.

[Cristina Sarmiento 1E]

Negative delta G means the reaction is spontaneous.

[Alejandra Rios 1L]

A -ΔG indicates that the reaction is spontaneous and exothermic, while a +ΔG indicates that the reaction is non spontaneous and endothermic. However, when dealing with a +ΔG we can say that the reverse reaction is favored since it is spontaneous in the reverse direction

[Jeremiah Samaniego 2C]

When delta G is negative, the process is spontaneous. When delta G is positive, the forward process is not spontaneous, but the reverse process is spontaneous.

[Christy Zhao 1H]

On page 348 of the textbook, there is a helpful diagram that shows that a negative change in Gibbs free energy is spontaneous.

[CalebBurns3L]

Negative Delta G means spontaneous because energy is leaving the system.
