What is the physical meaning Gibb's Free Energy?
Is it the amount of energy present in a system to perform chemical reaction(work) or the energy left after a reaction occurs which are given by the delta G values, i.e. when negative the reaction releases energy and when positive it absorbes energy?

Change of free energy of Gibbs to the equally most useful work which is made by system in isobaric and isothermal process. We can determine spontaneity of course of reaction by Gibbs's energy: ∆G> 0 (not spontaneous) ∆G=0 (equilibrium) or it is reversible ∆G <0 (spontaneous)
