How does Gibbs free energy relate to Thermodynamics ?

The Gibbs free energy of the system is a state function because it is defined in terms of thermodynamic properties that are state functions. Such as entropy and enthalpy.

Thermodynamics concerns the beginning and end states of a reaction, which delta G gives us information about. Delta G tells the difference between the free energy at the end of the reaction and at the beginning.

The Gibbs free energy of a system at any moment in time is defined as the enthalpy of the system minus the product of the temperature times the entropy of the system. The Gibbs free energy of the system is a state function because it is defined in terms of thermodynamic properties that are state functions.

Adding on to what others have said, we use Gibbs free energy to determine if a certain reaction is thermodynamically favorable. If the Gibbs free energy of a reaction is negative, then the reaction is thermodynamically favorable and spontaneous.

Gibbs free energy determines whether or not a reaction is spontaneous (or thermodynamically favorable) in a given direction. A reaction with a negative gibbs free energy is said to be spontaneous while a reaction with a positive gibbs free energy is non-spontaneous.

Delta G of Gibbs' free energy determines whether something is thermodynamically favorable. This is basically spontaneity. A negative delta G is spontaneous.

Gibbs essentially is a state function that is used primarily in identifying if a reaction is spontaneous (deltaG<0) or non-spontaneous (deltaG>0). It also helps connect a lot of other thermodynamic properties

Thermodynamics mostly concerns state properties. These are things that focus on the final and initial values without much concern for what is happening in between. Gibbs Free Energy (delta G) is one of these state properties and also helps us to calculate other thermodynamic properties.

Gibbs acts as a state function and determines whether or not a reaction is spontaneous in a given reaction.

Gibbs free energy allows us to know whether a reaction is favorable or unfavorable.

Gibbs free energy also tells us if the reaction is spontaneous or not based on the sign (positive number or negative number)
