standard equilibrium constant, \(K^{\unicode{x26ac}}\), \(K\)

Synonym: thermodynamic equilibrium constant
https://doi.org/10.1351/goldbook.S05915
Quantity defined by \(K^{\,\unicode{x26ac}} = \text{e}^{-\Delta _{\text{r}}G^{\,\unicode{x26ac}}/R\ T}\) where \(\Delta _{\text{r}}G^{\,\unicode{x26ac}}\) is the standard reaction Gibbs energy, \(R\) the @G02579@ and \(T\) the @T06321@. Some chemists prefer the name thermodynamic equilibrium constant and the symbol \(K\).
