A) T > 298 K
B) T < 425 K
C) T > 425 K
D) All temperatures
Correct Answer: C
Solution :
\[\because \] \[\Delta G=\Delta H-T\Delta S\] For a reaction to be spontaneous, \[\Delta G=-ve\] i.e., \[\Delta H<T\Delta S\] \[\therefore \] \[T>\frac{\Delta }{\Delta S}=\frac{35.5\times {{10}^{3}}J}{83.6\,J{{K}^{-1}}}\] i.e., T > 425 KYou need to login to perform this action.
