Textbook Question
Chapter 17, Problem 17.109QE
Chemists and engineers who design nuclear power plants have to worry about high-temperature reactions because it is possible for water to decompose.
- (a) Under what conditions does this reaction occur spontaneously?
2H2O(g) → 2H2(g) + O2(g)
- (b) Under conditions where the decomposition of water is spontaneous, do nuclear engineers have to worry about an oxygen/hydrogen explosion? Justify your answer.

Ethylene (C2H4) plays an important role in the ripening of certain fruits and vegetables. It is sometimes supplemented under controlled conditions at produce—processing facilities but is also produced naturally by many fruit-bearing plants. Although the actual process by which plants produce ethylene is a complex one, imagine that it is produced by the simple breakdown of glucose according to the equation:
C6H12O6 (s) à 3 C2H4 (g) + 3 O2 (g)
Given S°= 212.1 J/molK, DG°= -910.56 kJ/mol and DH°= -1274.5 kJ/mol for C6H12O6 (s).
a.) Determine the sign of DS° for the reaction.
b.) Calculate DS° for the reaction.
c.) Using the tabulated DG° values in the appendix, calculate DG° for the reaction.
d.) Above what temperature (in °C) is the reaction spontaneous? Hint: you will first have to calculate DH° using tabulated values.
Write and balance the reaction for the complete combustion of ethane, C2H6. (Use the lowest possible coefficients.)
21. Solid ammonium carbamate, NH4CO₂NH2, decomposes to ammonia and carbon dioxide when it sublimes:
NH4CO₂NH2 (s) = 2NH3(g) +CO2 (g)
Imagine a sample of ammonium carbamate is allowed to decompose in an evacuated sealed container at 25°C
(evacuated means no gas components at the start of the reaction). The decomposition is endothermic, and the
Kp at 25°C is 2.3 x104.
Tuming
a. What are the partial pressures of NH3 and CO₂ at equilibrium? What is the total pressure in the container
at equilibrium? Assume the mixture is ideal.
