Question

Use the data in Appendix B in the textbook to calculate ΔH∘ and ΔS∘ for each of the following reactions. From the values of ΔH∘ and ΔS∘, calculate ΔG∘ at 25 ∘C and predict whether each reaction is spontaneous under standard-state conditions.
Part A
2SO2(g)+O2(g)→2SO3(g)

ΔH∘ =
kJ

Part B
Express your answer using four significant figures.

ΔS∘ =
J/K

Part C
Express your answer using four significant figures.

ΔG∘ =
kJ

Part D

spontaneous under standard-state conditions
nonspontaneous under standard-state conditions
