Gibbs Free Energy

Postby Jessica Helfond 2F » Fri Feb 22, 2019 2:22 pm

Could someone explain what Gibbs free energy actually is? And how does that relate to entropy and enthalpy?

Gibbs free energy is the available energy that can do useful work. They are related by the equation delta G= delta H- T*delta S.

I believe that Gibbs Free Energy is a term that scientists defined based solely on enthalpy and entropy. For example, a machine cannot directly find the delta G of a reaction on its own. The machine will look at the change in enthalpy and entropy to calculate delta G.
