In general Gibbs free energy is NOT constant. Gibbs free energy can be translated into chemical potential and differences in chemical potential are what drive changes - whether it be chemical reactions, phase changes, diffusion, osmosis, heat exchange or some other thermodynamic function.

Who calculate the value of universal gas constant 'G'?
The universal gas constant is denoted by R = 8.314 J/kgK, (but not G which denotes the Gibbs free energy of a given reaction at given conditions.
Where can one learn more about the Gibbs Free Energy theory?
One may go to the local library to research Gibbs Free Energy theory. One may also look towards Wikipedia, Ebooks, Boundless or Chemistry About to find information about the Gibbs Free Energy theory.
What does the gibbs free energy predict?
It predicts whether or not a reaction will be spontaneous.
How does Gibbs free energy predict spontaneous?
If G < 0, the reaction is spontaneous.
Is the Gibbs free energy negative in the spontaneous reaction?
Yes, as long as the entropy of the universe increases.
What affects the magnitude of delta G?
Delta G is the change in Gibbs free energy. Gibbs Free energy is defined as:- G= H-TS at constant temperature so the factors ar the change in enthalpy (H) and entropy (S)
What are thermodynamics?
Thermodynamic properties are specific volume, density, pressure, and temperature. Other properties are constant pressure, constant volume specific heats, Gibbs free energy, specific internal energy and enthalpy, and entropy.

What is the Gibbs free energy of the reaction at 300K?
150
Use the Gibbs free energy equation shown below to find the Gibbs free energy change for the formation of potassium chloride at 25°C?
-225.3 KJ
Using Gibbs free energy equation what is the Gibbs free energy change for the synthesis of carbon disulfide at 25C?
δg = (-992.0) - (298)(-294.6)(1/1000)

Gibbs quantity of maximum possible work?
Gibbs free energy represents the maximum reversible work that can be extracted from a system at constant temperature and pressure. It combines the system's enthalpy and entropy to predict whether a reaction is spontaneous. The change in Gibbs free energy (∆G) determines whether a reaction will proceed spontaneously or not.
Why is hydrogen combustible?
Fundamentally, because the Gibbs free energy of elemental hydrogen and oxygen is substantially greater than the Gibbs free energy of the water formed by their chemical reaction, and the activation energy for the reaction is not excessively high.
What is the value equal to the enthalpy minus temperature times entropy?
free energy. this is gibbs free energy in biological systems
What is a negative Gibbs free-energy value an indication of?
Spontaneous reaction
What does the gibbs free energy predict?
It predicts whether or not a reaction will be spontaneous.
