I read that that for dG and dH, there is a standard pressure, but NO standard temperature.
Q1-Why not?
Q2-So...things don't change based on temperature? So in dG=dH-TdS, this relationship will hold true no matter the temperature? How can that be...dG and dH have fixed values, and the entropy is also fixed by whatever the reaction is, no? (meaning, AB(s)->A(g)+B(g) has a set entropy, no?)
How can the reaction hold true for all temperatures?
