dS isn't an important focus, because the reactions themselves are taking that Gibbs free energy.

The Gibbs free energy is just -T times the entropy change, at constant pressure. It's just a proxy for the total entropy.

"The Gibbs free energy is just -T times the entropy change, at constant pressure. It's just a proxy for the total entropy."

Since I mentioned reactions I thought it was clear, but...

delG = delH -T*delS

The enthalpy, or heat of reaction is larger than T*delS and what drives "the signal".
