Consider the following reaction: 4 NH3(g) + 5 O₂(g) — 6 H₂O(g) + 4 NO(g) Calculate AG at 547 K for a mixture of 2.3 bar NH3(g), 3.0 bar O₂(g), 4.9 bar H₂O(g), and 3.6 bar NO(g). State whether or not the reaction is spontaneous at these conditions. **AG° values can be found in textbook appendix** O-929 kJ/mol; spontaneous -929 kJ/mol; nonspontaneous O 929 kJ/mol; spontaneous 929 kJ/mol; nonspontaneous
