DQuestion 3 Ipts At what temperature range is the reaction below, which is endothermic, spontaneous? C12(g) 2 Cl(g) ? O At all temperatures O Low temperatures O High temperatures O At no temperatures Previous Next
Solution
Since the reaction is endothermic as given in the problem
Hence, Delta H > 0
For the reaction to be spontaneous, Delta G must be negative
Delta G = Delta H - T * Delta S
Delta S will be positive for this reaction since entropy is increasing because we are forming 2 moles of gaseous products at output
Hence when temperature is high, the Delta G will become negative making it spontaneous
Hence the correct answer is C (At high temperatures)
