Question

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

1. Use data in Appendix C in the textbook to predict how ΔG° for the reaction varies with increasing temperature.
2. Calculate ΔG° at 800 K, assuming that ΔH° and ΔS° do not change with temperature.
3. Under standard conditions is the reaction spontaneous at 800 K?
4. Calculate ΔG° at 1000 K.
5. Is the reaction spontaneous under standard conditions at this temperature?
