Free energy is a measure of capacity of a system to do work. Now if the process occurring is spontaneous; indicates that work is done by the system so the free energy goes on decreasing and it is negative and the entropy (which is maximum disorder of the system) increases and it is positive.
And on the other hand if the process is non spontaneous then the free energy increases and is positive and the entropy goes on decreasing and it is negative.
And on the other hand if the process is non spontaneous then the free energy increases and is positive and the entropy goes on decreasing and it is negative.

DG = dH-TdS so, free energy decreses if dS positive (increase in entropy).
