ΔH = –92kJ


In the Haber process for the production of ammonia, what can you say about the spontaneity of the reaction with the available information in the passage?

A The reaction is definitely spontaneous
B The reaction is definitely nonspontaneous
C The reaction is endothermic, and definitely spontaneous
D Cannot be predicted accurately without further data
Ans. D We cannot predict the spontaneity of the reaction accurately based on the information given in the passage. The only fact that we know regarding the reaction is that it has a ΔH value of –92 kJ. Based on that alone, it is not possible to predict the spontaneity accurately.
