if d(G/T)=(-H/T^2)dT

then why can it also equal
d( delta G/T)= -delta H/T^2?
 
Physics news on Phys.org
unless delta=1 then all those things can't be equal.
 
matt,I think that's a thermodynamic relationship. So delta G signifies the change in Gibbs energy between the initial and final states
ie, delta G = G_f - G_i
 
The point I was making was that the question is badly written. We shouldn't have to guess what the symbols mean.
 
sorry about that!
you're right~
it's a thermodynamics relationship, and I'm confused about why the second equation is right...
