A) 2112.3 K
B) 136.7K
C) 275.8 K
D) 1112.5K
Correct Answer: D
Solution :
According to Gibbs-Helmholtz reaction, \[\Delta G=\Delta H-T\Delta S\] For a spontaneous reaction, \[\Delta G<0\] i.e., \[\Delta H-T\Delta S<0\] or \[T>\frac{\Delta H}{\Delta S}\] or \[T>\frac{178\times 1000}{160}\] \[T>1112.5\,K\] \[\therefore \] For spontaneous process, minimum temperature must be 1112.5 K.You need to login to perform this action.
