Place the following in order of decreasing standard molar entropy. N₂O₄(g)NO(g)NO₂(g)

Question

Quizplus · Accepted Answer

Standard molar entropy generally increases with the complexity and size of the molecule, as well as the number of atoms and degrees of freedom (rotational, translational, vibrational). NSO (with the highest molecular complexity and number of atoms) has the highest entropy, followed by NOS, and then NO with the least complexity and fewest atoms.
