A chemical reaction is spontaneous at 298 K but non-spontaneous at 350 K . Which one of the following following s true for this reaction ?A. `{:(Delta G,DeltaH ,DeltaS),(-,-,+):}`B. `{:(Delta G,DeltaH ,DeltaS),(+,+,+):}`C. `{:(Delta G,DeltaH ,DeltaS),(-,+,-):}`D. `{:(Delta G,DeltaH ,DeltaS),(-,-,-):}` |

Answer» Correct Answer - D 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. |
