MCQ
The occurrence of a reaction is impossible if
  • A
    $\Delta H$ is $+ve$ ; $\Delta S$ પણ $+ ve$ પરંતુ  $\Delta H < T\Delta S$
  • B
    $\Delta H$ is $-ve$ ; $\Delta S$ is also $-ve$ but $\Delta H\, > \,T\Delta S$
  • C
    $\Delta H$ is $-$  $ve$ ; $\Delta S$ is $+ $ $ve$
  • $\Delta H$ is $ + $ $ ve$ ; $\Delta S$ is $-$ $ve$

Answer

Correct option: D.
$\Delta H$ is $ + $ $ ve$ ; $\Delta S$ is $-$ $ve$
(d) $ + \,\,ve\,\,\Delta H$and $ - \,\,ve\,\,\Delta S$ both oppose the reaction.
