 Homework Statement:

I have a question which asks:
What does it mean that deltaG_zero = 0?
 Relevant Equations:
 .
At equilibrium, we know that deltaG = 0. But what about deltaG_zero, i.e. the standard Gibbs free energy? When is deltaG_zero = 0?
In the solution manual it says that it means that K = 1, but by calculating an equilibrium constant you are already stating that we are at equilibrium? I.e. that deltaG = 0, and K = 1 implies deltaG_zero = 0. A bit confused by this.
