Consider the following reaction between oxides of nitrogen: NO2(g) + N2O(g) 3 NO (g) (a) Use

Question:

Consider the following reaction between oxides of nitrogen:
NO2(g) + N2O(g) → 3 NO (g)
(a) Use data in Appendix C to predict how ΔG° for the reaction varies with increasing temperature.
(b) Calculate ΔG° at 800 K, assuming that ΔH° and ΔS° do not change with temperature. Under standard conditions is the reaction spontaneous at 800 K?
(c) Calculate ΔG° at 1000 K. Is the reaction spontaneous under standard conditions at this temperature?
