Consider the following reaction between oxides of nitrogen:NO 21 g 2 + N 2 O 1 g 2 ¡ 3 NO 1 g 2 (a) Use data in Appendix C topredict how ∆ G for the reac-tion varies with increasingtemperature. (b) Calculate ∆ G at 800 K, assuming that H ° and S °do not change with tem-perature. Under standard conditions is thereaction sponta-neous at 800 K? (c) Calculate ∆ G at 1000 K. Is thereaction spontaneous under standard conditions at thistemperature?
