A) 2.06 K
B) 31.6 K
C) 43.7 K
D) 53.4 K
Correct Answer: C
Solution :
Since, \[\Delta G=\Delta H-T\Delta S.\] At equilibrium \[\Delta G=0\] \[\therefore \] \[\Delta H=T\Delta S\] Given \[\Delta H=-743.1\,\text{J/mol}\text{.}\] \[\Delta S=-17.0\,J\,{{K}^{-1}}\,mo{{l}^{-1}}\] \[\therefore \] \[\frac{-743.1}{-17.0}=T\] \[T=43.7\,K\] At this temperature solid I and II are in equilibrium. Hence, the correct option is [c].You need to login to perform this action.
