Consider the endothermic reaction:
N₂(g) + 2 H₂(g) → N₂H₄(l)
The entropy change of this reaction is ________ and the enthalpy change is ________,so at a very high temperature,this reaction is probably ________.

Question

Quizplus · Accepted Answer

The reaction involves a decrease in the number of gas molecules, leading to a decrease in entropy (unfavorable). It is endothermic, meaning the enthalpy change is positive (unfavorable). At high temperatures, both unfavorable entropy and enthalpy changes make the reaction nonspontaneous.
