Standard Gibbs Free Energy doesn't change?
Does standard Gibbs free energy stay the same for the molecule at whatever condition? I thought it changed based on temperature due to the equation delta G standard = delta H standard - T*delta S standard. So when you plug in any temperature, you get a delta G standard based on the temperature. However, I keep hearing that delta G standard stays the same while delta G can change. Can someone clarify this for me?

Delta G standard is for when the temperature is 273.15K ONLY. Once you change T, you are no longer calculating the standard delta G but just delta G.
