Is a symbol which stands for the value equal to the entirely enthalpy minus the temperature times enthropy . It can be used to determine if a reaction will take place?

The change in Gibbs Free Energy (∆Gº) predicts if a reaction is spontaneous or not. The equation for this is ∆G = ∆H - T∆S where ∆H is the change in enthalpy, T is temperature in Kelvin, and ∆S in change in entropy.

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.


Is Gibbs free energy constant?

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.
