Consider the following three reactions:

(a) For each of the reactions, use data in Appendix C to calculate ΔH°, ΔG°, and ΔS° at 25°C.
(b) Which of these reactions are spontaneous under standard conditions at 25°C?
(c) For each of the reactions, predict the manner in which the change in free energy varies with an increase in temperature.
