For the following example,identify the following. I 2 (l)→ I 2 (g)

The state change is from liquid (l) to gas (g), which is endothermic (requires energy input) and thus has a positive ΔH. Meanwhile, there is an increase in disorder (gas has more freedom of motion than liquid), so ΔS is also positive. Therefore, the correct choice is D, for a positive ΔH and a positive ΔS.
