A) \[\Delta H\,\,\,\,\,+ve\] \[\Delta S\,\,\,\,+ve\]
B) \[\Delta H\,\,\,\,\,-ve\] \[\Delta S\,\,\,\,-ve\]
C) \[\Delta H\,\,\,\,\,-ve\] \[\Delta S\,\,\,\,+ve\]
D) \[\Delta H\,\,\,\,\,+ve\] \[\Delta S\,\,\,\,-ve\]
Correct Answer: A
Solution :
For spontaneity \[\Delta G=-ve\] \[\Delta G=\Delta H-T\Delta S\] \[\Delta \] H, for endothermic process \[+ve\]. At lower temperature, \[\Delta S+ve\]. Hence, \[\Delta G=+ve\] But at high temperature \[T\Delta S\] will be greater than \[\Delta H,\] hence \[\Delta G=-ve\], spontaneous.You need to login to perform this action.
