## Wikipedia - Massenwirkungsgesetz 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 $$K$$.
