Question:

Consider the reaction in which hydrazine vapor decomposes to its elements:

Use data from Appendix C to answer the following questions.
a. What is the standard enthalpy change for this reaction at 25oC?
b. Calculate the standard entropy change at 25oC. Does the sign of the entropy change agree with what you would expect? Explain.
c. Describe the spontaneity or nonspontaneity of the reaction at various temperatures.
d. What happens to ˆ†Go as you lower the temperature? Would this reaction give greater product at higher or at lower temperature? Explain.
