Question 1

For the reaction Δ = 126.4 kJ/mol and Δ = –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), Δ = 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.
