This article may be too technical for most readers to understand. In particular, this will be true if the system is experiencing any number of internal chemical reactions on its path to equilibrium.

This section may dnergi confusing or unclear to readers. As discussed in the overview, if the temperature and pressure are held constant, the Gibbs free energy is a negative proxy for the change in total entropy of the universe.

Gibbs energy or Gibbs function ; also known as free enthalpy [1] to distinguish it from Helmholtz free energy is a thermodynamic potential that can be used to calculate the maximum of reversible work that may be performed by a thermodynamic system at a constant temperature and pressure isothermalisobaric.

Zeroth First Second Third. Unsourced material may be challenged and removed. Dengan kata lain, ini berlaku untuk sistem terbuka.

Gibbs free energy was originally defined graphically. In his second follow-up paper, “A Method of Geometrical Representation of the Thermodynamic Properties of Substances by Means of Surfaces”, published later that year, Gibbs added in the third coordinate of the energy of the body, defined on three figures. Energi Gibbs juga dirujuk sebagai G juga merupakan potensial termodinamika yang diminimalkan saat sistem mencapai kesetimbangan pada tekanan dan suhu konstan.


This coupling allows endergonic reactions, such as photosynthesis and DNA synthesis, to proceed without decreasing the total entropy of the universe.

Material properties Property databases Specific heat capacity.

Helmholtz Gibbs

The Historical Background of Chemistry. A chemical reaction will or can proceed spontaneously if the brbas in the total entropy of the universe that would be caused by the reaction is nonnegative. The Gibbs energy also referred to as G is also the thermodynamic potential that is minimized when a system reaches chemical equilibrium at constant pressure and temperature.

Concepts in physics State functions Thermodynamic free energy. Please help improve this fibbs by adding citations to reliable sources.

The condition of stable equilibrium is that the value of the expression in the parenthesis shall be a minimum. Laws Zeroth First Second Third. The temperature dependence of the Gibbs energy for an ideal gas is given by the Gibbs—Helmholtz equationand its pressure dependence is given by. Also, the circle notation is not well explained even in the one case where it is attempted.

In particular, the physical situation is not explained. InWillard Gibbs gibs A Method of Geometrical Representation of the Thermodynamic Properties of Substances by Means of Surfacesin which he sketched the principles of his new equation that was able to predict or estimate the tendencies of various natural processes to ensue when bodies or systems are brought into contact.


Ekspresi untuk perubahan reversibel yang sangat kecil dalam energk bebas Gibbs sebagai fungsi dari ‘variabel gibsb p dan T, untuk sistem sistem terbukamengalami operasi gaya eksternal misalnya listrik atau magnet X iyang menyebabkan parameter eksternal sistem a i mengalami perubahan sejumlah d a iendrgi diturunkan mengikuti Hukum Pertama untuk proses reversibel:. Halaman ini terakhir diubah pada 26 Novemberpukul The Gibbs free energy total differential natural variables may be derived by Legendre transforms of the internal energy.

If we wish to enwrgi in a single equation the necessary and sufficient condition of thermodynamic equilibrium for a substance when surrounded by a medium of constant pressure p and temperature Tthis equation may be written: InScottish physicist James Clerk Maxwell used Gibbs’ figures to make a 3D energy-entropy-volume thermodynamic surface of a fictitious water-like substance.
