Spontaneity

[Mahir_Hasan2C]

How does G relate to a reaction being spontaneous?

[Hovik Mike Mkryan 2I]

Hello, if delta G is negative it results in the reaction being spontaneous because the forward reaction is favorable and happens naturally without extra needed energy. Hope this helped!

[Jaira_Murphy_2D]

Can someone explain this from the textbook? "At constant temperature and pressure, the direction of spontaneous change is the direction of decreasing Gibbs free energy."

[Isabelle Fontanilla 1I]

"At constant temperature and pressure, the direction of spontaneous change is the direction of decreasing Gibbs free energy."
The more negative the Gibbs Free Energy value is, the more spontaneous a process becomes.

When delta G is negative, the reaction is spontaneous because this means that it does not need energy to proceed and will naturally follow the second law of thermodynamics by increasing in entropy.
