What is the Relationship between Thermodynamic Delta and Change in Enthalpy?

[asdf1]

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

then why can it also equal
d( delta G/T)= -delta H/T^2?

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...
