How does G relate to a reaction being spontaneous?

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!

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."

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.
