Question

Quizplus · Accepted Answer

Molar entropy generally increases with increasing molecular complexity and size. Therefore, N₂H₄ will have the highest molar entropy, followed by HCl and then He, which has the lowest molar entropy due to its small size and lack of complexity. Hence, option D is the correct answer.
