Question 1

For the reaction

ΔH° = 126.4 kJ/mol and ΔS° = –74.9 J/K·mol.

At 381°C, what is ΔG ?

◦ 154.9 kJ/mol
◦ 49.1 kJ/mol
◦ 175.4 kJ/mol
◦ 77.4 kJ/mol
◦ 157.6 kJ/mol

Question 2

For the reaction 2HF(g)

H₂(g) + F₂(g), ΔG° = 38.3 kJ, at 1000 K. If, at this temperature, 5.00 moles of HF(g), 0.500 moles of H₂(g), and 0.75 moles of F₂(g) are mixed in a 1.00-L container:

◦ Some HF will decompose (to yield H₂ and F₂).
◦ The system is at equilibrium.
◦ Some HF will be formed (from H₂ and F₂).
◦ Not enough data are given to answer this question.
◦ None of these are correct.
