Yes, and that means dH must be large(negative) eough to off set dS.
BTW, a little urgent is like being a little pregnant.
For oxidation of iron
4Fe+3O2=2Fe2O3
the entropy change is -549.45JK^-1mol^-1 at 298K. Though it has negative entropy change in the reaction is spotaneous.why?
(Delta r H theta ∆rH°=-1648×10^3 J ml^-1.
Is it because ∆G is negative????
