Gibbs equilibrium

Postby Marc Farah 3D » Fri Jan 27, 2017 7:39 pm

Are equilibrium conditions when delta G = 0 or when delta G (not) =0? Why? Also why is the system not at equilibrium if Gr doesn't equal Gp?

Equilibrium occurs when delta G= 0. Having delta G (not)= 0 is nearly impossible. This is the equilibrium because when delta G = 0, no change in energy can occur while also being a spontaneous process. Any movement from this point will require some sort of energy. If Gr is not equal to Gp then delta G will not be 0 since delta G is the difference between the two.
