When ΔH is negative and ΔS is negative, Δ G will be in the form of the negative at the low temperature.
If the ΔH is in the state of the positive and Δ S will be in the form of the negative.
But the ΔG will not be negative at the any temperature.
Even it can be no spontaneous reaction taken place finally it c will change the free energy of reaction that an predict when a reaction is completely feasible.
