## K

$\Delta G^{\circ}= \Delta H^{\circ} - T \Delta S^{\circ}$

$\Delta G^{\circ}= -RT\ln K$

$\Delta G^{\circ}= \sum \Delta G_{f}^{\circ}(products) - \sum \Delta G_{f}^{\circ}(reactants)$

### K

Thermodynamically-speaking does K, in addition to being the equilibrium constant, indicate standard conditions?

### Re: K

K is the equilibrium constant for a reaction at a given temperature; therefore, its value changes depending on T. Unless you are told the K value you are given is at standard temperature (273K), you cannot assume it is standard.
