Gibbs Free Energy in relation to H and S

Postby Sophia Diaz - Dis 1B » Sun Feb 17, 2019 12:59 pm

Hey y'all!

So I'm having trouble understand what Gibbs Free Energy is and how it relates to enthalpy and entropy. I know what the equation is to solve it but why can you solve for G using G (prod) - G (react) if G, H, and S are all different?

Thanks so much!

I think it all comes back to this equation: ∆G = ∆H - T∆S

you can solve for using because Gibbs Free Energy is defined by the state functions enthalpy and entropy, and it too is a state function.

And just as a reminder, a state property is not dependent on the path taken to obtain that state.
