For this problem, we need to do the following steps:

*Step 1:* Calculate ΔH˚_{rxn}.

*Step 2:* Calculate ΔS˚_{rxn}.

*Step 3:* Use ΔH˚_{rxn} and ΔS˚_{rxn} to calculate for ΔG˚_{rxn}.

Consider the following three reactions. For each of the reactions, use data in Appendix C in the textbook to calculate ΔH°, ΔG°, and ΔS° at 25 °C.

3) BaO(s)+CO_{2}(g)→BaCO_{3}(s)
