Chapter 12, Problem 46QRT

Using the data of Table 12.1, predict which of these reactions is product-favored at 25 °C. Then, place all the reactions in order from most reactant-favored to most product-favored.

1. (a) $2{\text{NH}}_3(\text{g})\rightleftharpoons {\text{N}}_2(\text{g})+3{\text{H}}_2(\text{g})$
2. (b) ${\text{NH}}_4^{+}(\text{aq})+{\text{OH}}^{-}(\text{aq})\rightleftharpoons {\text{NH}}_3(\text{aq})+{\text{H}}_2\text{O}(\ell )$
3. (c) $2\text{NO}(\text{g})\rightleftharpoons {\text{N}}_2(\text{g})+{\text{O}}_2(\text{g})$
