Which of the following substances under equal conditions and in the same phase has the greatest molar entropy? A)NO B)NO₂ C)N₂O₃ D)N₂O₄ E)N₂O₅

Question

Quizplus · Accepted Answer

The molar entropy of a substance increases with an increase in the number of particles and complexity of the molecule. Among the given options, option E has the greatest number of particles and complexity due to the presence of three different elements and a higher number of oxygen atoms, which contributes to numerous vibrational and rotational states, resulting in higher entropy. Therefore, N₂O₅ has the greatest molar entropy.
