A) 300 K
B) 30 K
C) 100 K
D) \[~300{{\,}^{o}}C\]
Correct Answer: A
Solution :
\[\because \] \[\Delta G=\Delta H-T.\Delta S\] \[\Delta G=30000-(T\times 100)\,J\,mo{{l}^{-1}}\] For spontaneous process AG should be negative, i.e.,\[\Delta G<0\] and this occurs when \[T\Delta S>\Delta H.\] \[T>\frac{\Delta H}{\Delta S}\] \[T>\frac{30000}{100}\] \[T>300\,K\]You need to login to perform this action.
