A) \[\Delta H<0;\,\Delta S<0\]
B) \[\Delta H>0;\,\Delta S>0\]
C) \[\Delta H<0;\,\Delta S>0\]
D) \[\Delta H>0;\,\Delta S<0\]
Correct Answer: B
Solution :
[b] \[\Delta G=\Delta H-T\Delta S\] |
For an endothermic reaction \[\Delta H=+ve\] |
[less molecules \[\to \] more molecules], |
\[\Delta H=+ve\] |
\[\therefore \] \[T\Delta S>\Delta H,\] and \[\Delta G=-ve\] |
Hence, the reaction occurs spontaneously. |
