A) 4 K
B) 20 K
C) 5 K
D) 12 K
Correct Answer: C
Solution :
For a process to be spontaneous, \[\Delta \,G<0\] & \[\Delta G=\Delta H-T\Delta S\] at equillibrium \[\Delta G=0\,,\,\,\,\therefore \,\,\Delta H={{T}_{e}}\Delta S\], \[\therefore \,\,\,\,{{T}_{e}}=\frac{\Delta H}{\Delta S}\,\,=\,\,\frac{200}{40}\,\,=\,\,5\,k\] \[\therefore \] If \[T>{{T}_{e}},\text{ }\Delta G<0\] and the process will be spontaneousYou need to login to perform this action.
