Gibbs Free Energy vs. Standard Gibbs Free Energy

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

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

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

Gibbs Free Energy vs. Standard Gibbs Free Energy

I was wondering what the difference between Gibbs Free Energy vs. Standard Gibbs Free Energy is.

Re: Gibbs Free Energy vs. Standard Gibbs Free Energy

Gibbs free energy is delta G, and standard is delta G not at certain conditions. I believe it's 1 atm and 273.15 Kelvin

Re: Gibbs Free Energy vs. Standard Gibbs Free Energy

The standard Gibbs Free Energy is fixed for a certain reaction and temperature. It is also under standard conditions and the difference between the Gibbs free energy of pure products and reactants.

Re: Gibbs Free Energy vs. Standard Gibbs Free Energy

Standard Gibbs Free Energy is at specific conditions, whereas just gibbs free energy can be at any given conditions!
