Without doing any calculations, determine the sign of AS and ASu, for each chemical reaction. In addition, predict under what temperatures (all temperatures, low temperatures, or high temperatures), if any, the reaction is spontaneous. a. CHg(g) + 5 0(g) 3 CO,(g) + 4 H,O(g) AHan = -2044 kJ b. N2(g) + O2(g) 2 NO(g) c. 2 N,(g + O:(g) 2 N,0 d. 4 NH,(g) + 5 0,(g) 4 NO(g) + 6 H,O(g) AHan = +182.6 kJ AHan = +163.2 kJ AHan = -906 kJ
