The values of DeltaH and DeltaS for the reaction, C("graphite") + CO_

1.	The values of DeltaH and DeltaS for the reaction, C("graphite") + CO_(2)(g) to 2CO(g) are 170 kJ and 170 J/K respectively. This reaction will be spontaneous at
Answer» 910 K 1110 K 510 K 710 K Solution :For a spontaneous process , `DeltaG` MUST be negative. Here, `DeltaG`will be negative when `T DELTAS gt DeltaH` `DeltaH = 170 kJ = 170000`J `DeltaS - 170 J K^(-1)"mol"^(-1)` `TDeltaS gt DeltaH` only when ` T = (DeltaH)/(DeltaS) = (170000)/(170) = 1000K` i.e greater than 1000 K or 1110 K.
