Help with thermodynamic delta

  1. Dec 11, 2005 #1
    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...
