I forgot to mention, this is in the context of partial molar properties, so i suppose this molar ΔG is referred to a solution. Right? In that case, is it a change due to mixture?

Yes, this is a homework question. I'm pretty sure the answer is related to equilirium and spontaneity, becuause my teacher always rembembered us those 3 values of ΔG and their meaning. But now that ΔG is molar, i'm not sure what happens with the equilibrium and spontaneity.

What's the thermodynamic meaning of these molar Gibbs free energy values? I know that when it is ΔG>0 , it means there is no spontaneity, when ΔG=0 there is equilibrium, and when ΔG<0, there is spontaneity. But what happens when G is molar?
