I get the answer, no problem. Math makes sense. Perhaps I don't like the way the question is worded, or maybe it can be worded better. But my issue is that a lower temperature, let's say 1K, still gives a negative ΔG (since subtracting a small negative would make negligible impact on the ΔH which is a large negative).
Also, according to this chart:

this scenario (negative ΔH and negative ΔS) is spontaneous at low temperatures.
What am I missing??! It's probably something obvious.
Help and thanks in advance!

Was ΔS supposed to be positive? Even so, the answer would be the wrong sign. :|
