For the reaction CO (g) + (1)/(2) O_(2) (g) rarr CO_(2) (g) Delta H and Delta S are -283 kJ and -87 J K^(-1), respectively. It was intended to carry out this reaction at 1000,1500,3000, and 3500 K. At which of these temperatures would this reaction be thermodynamically spontaneous? |

Answer» 1500 and 3500K For a spontaneous reaction `DeltaG` should be negative `DeltaH=-234kJ,DeltaS=-87JK^(-1)` Hence reaction will be spontaneous when `DeltaHgtT.DeltaS`. THEREFORE at 1000, 1500 and 3000 K the reaction would be spontaneous. |
