Chemical Thermodynamics Question 383

Question: The favourable conditions for a spontaneous reaction are

Options:

A) $ T\Delta S>\Delta H,\Delta H=+ve,\Delta S=+ve $

B) $ T\Delta S>\Delta H,\Delta H=+ve,\Delta S=-ve $

C) $ T\Delta S=\Delta H,\Delta H=-ve,\Delta S=-ve $

D) $ T\Delta S=\Delta H,\Delta H=+ve,\Delta S=+ve $

Show Answer

Answer:

Correct Answer: A

Solution:

  • $ \Delta G=\Delta H-T\Delta S,\Delta His+ve, $

$ \Delta S $ is $ +ve;T\Delta S>\Delta H $ for spontaneous process. It will make $ \Delta G,-ve $
