Which of the following reactions has the greatest negative change in entropy?
C) 2 NO (g) + O2 (g) --> NO2 (g)
D) H2O (g) --> H2O (l)
There is a typo in this question, i feel like it should be 2NO2 (g) for C. but does anyone know discretely how to really evaluate these kinds of questions, comparing phase changes with mole changes?
Like let's say you had
A) 3X (g) --> 1Y (g)
B) 3Y (g) --> 1Z (g)
the entropy change could be A > B, B > A, or A = B depending on the molecules, right? So basically a question like that will never be seen?
Now let's say you had
A) 1X (g) --> 1X (l)
B) 1X (g) --> 1X (s)
obviously greatest negative entropy change Must occur in B, right?
Now let's say you had
A) 2X (g) --> 1Y (g)
B) 1X (g) --> 1X (l)
C) 100000000X (g) --> 1Y (g)
Then C has a greater negative entropy change than A, but is there a point at which something like C (molar change) becomes a greater negative entropy change than a phase change that occurs that happens in B?
Thanks for the thoughts!
