Gibbs free energy

名詞

不可算名詞

(physics, chemistry, thermodynamics) The difference between the enthalpy of a system and the product of its entropy and absolute temperature: a measure of the useful work obtainable from a thermodynamic system at constant temperature and pressure.

日本語の意味

ギブス自由エネルギーとは、系のエンタルピーと、エントロピーと絶対温度の積との差を表す物理量で、一定温度・一定圧力下において取り出すことが可能な有効な仕事量の指標となる。

Gibbs free energy determines whether a chemical reaction at constant temperature and pressure can perform useful work.
