Gibbs free energy online calculation tool
Free energy refers to the part of the internal energy that can be converted into external work in a certain thermodynamic process. Free energy is defined in physical chemistry according to Helmholtz's constant free energy F and Gibbs's constant pressure free energy G.
Gibbs free energy is a kind of free energy. Gibbs free energy is also called Gibbs function, (Gibbs energy or Gibbs function; also known as free enthalpy) is an important parameter in thermodynamics, commonly used G, its definition is:
\(G = U − TS + pV = H − TS\)
Where U is the internal energy of the system, T is the temperature, S is the entropy, p is the pressure, V is the volume, and H is the enthalpy.
The differential form of Gibbs free energy is:
\(dG = − SdT + Vdp + μdN\)
Where μ is the chemical potential, that is, the average Gibbs free
energy of each particle is equal to the chemical potential.
