Main Question or Discussion Point

Can somebody please shed a little light on what this formula represents in the physical world?
And how could I solve it to get [tex]\Delta H[/tex]?

[tex]
\left[\frac{d\left(\frac{\Delta G}{T}\right)}{\delta T}\right]_p = \frac{\Delta H}{T^2}
[/tex]

humm ..looks like entropia. Or may be i'm completly wrong.

So, you are saying that
[tex]
\left[\frac{d\left(\frac{\Delta G}{T}\right)}{\delta T}\right]_p = \Delta S
[/tex]
?

no i wrote that, but i'm not saying that :-).
Anyway should be something about Gibbs-Helmholtz equation, but i don't remeber much about it.
So something about chemistry and termodinamics application usually.

[tex]

\left[\frac{\partial \Delta G}{\partial T}\right]_p = -\Delta S

[/tex]

But wait a reply from someone that know of what is talking about because i'm not sure.

Gibbs Helmholtz
Note d(1/T)/dT is 1/T2. Solve for H. Cancel terms.
So Enthalpy can be obtained from plot of deltaG/T vs 1/T
