According to the equation for Gibbs Free Energy, ∆G = ∆H - T∆S, for a process to be spontaneous, ∆G should be negative. Since ∆H and ∆S have opposite signs, in order to make ∆G negative, both ∆H and ∆S should have negative values. Hence, the correct choice is (F1F1F1S1∆F1F1F10H < 0 and F1F1F1S1∆F1F1F10S > 0).
