gibbs free energy of formation

How come a negative value of gibbs free energy is more stable compared to a positive value?

Gibbs free energy with a negative value, is a spontaneous reaction that produces more stable reactants compared to that of a non spontaneous reaction.

At a substances lowest energy state is its most stable configuration.

Like said above, Gibbs Free Energy is more stable when negative due to the spontaneity of the reaction. If the reaction isn't favorable/ spontaneous, then forcing it to happen may not result in the most stable products. I hope this helps! :)

If Gibbs Free Energy is negative, it is more stable because it refers to spontaneity of a reaction. Spontaneous reactions tend to yield more stable products as they are not "forced" to undergo a reaction, in contrast to a non-spontaneous reaction.
