A chemical reaction is spontaneous at 298 Kbut non-spontaneous at 350

1.	A chemical reaction is spontaneous at 298 Kbut non-spontaneous at 350 K . Which one of the following following s true for this reaction ?
Answer» `{:(DELTA G,DeltaH ,DELTAS),(-,-,+):}` `{:(Delta G,DeltaH ,DeltaS),(+,+,+):}` `{:(Delta G,DeltaH ,DeltaS),(-,+,-):}` `{:(Delta G,DeltaH ,DeltaS),(-,-,-):}` Solution :As reaction is spontaneous at LOW temperature and non-spontaneous at high temperature,i.e., `DELTAG` is-ve at low temperature and `+ve`at high temperature and `DeltaG =DeltaH - T DeltaS`, only ( e) in CORRECT.
