Greatest negative entropy?

[shyfox9p]

If you went from 6 moles of gas in your reactants to 2 moles of gas in your product. Entropy is changing right? You get a negative entropy value.
Now, if you had to compare the entropy of:
2NO(g) + O_2 (g)--> NO_2 (g)
H2O (g) --> H2O (l)
The liquid water will have a the greatest negative entropy because of the phase change?
The NO_2 gas has a negative entropy as well though right?

Anyone???

This seems pretty arbitrary but since the phase change occurred it would have a pretty big decrease in entropy, most likely more than going from 3 moles of gas to 2 moles of gas (after you balance the equation).

Thanks! It's a question from topscore and I've only seen comparisons with gases not with phase changes in chad's videos, destroyer, and bootcamp.
