题目

冶金工业、硝酸工业的废气废液中含氮化合物污染严重，必须处理达标后才能排放。 Ⅰ．用活性炭处理工厂尾气中的氮氧化物。 （1）已知：①4NH3(g)+5O2(g) ===4NO(g)+6H2O(l)  ΔH1=a kJ·mol−1 ②4NH3(g)+3O2(g) ===2N2(g)+6H2O(l)  ΔH2=b kJ·mol−1③C(s)+O2(g) ===CO2(g)   ΔH3=c kJ·mol−1 则反应C(s)+2NO(g)N2(g)+CO2(g)的ΔH=________。 （2）在容积不变的密闭容器中，一定量的NO与足量的C发生反应：C(s)+2NO(g)N2(g) + CO2(g)  ΔH= Q kJ·mol−1，平衡时c(NO)与温度T的关系如图1所示，下列说法正确选择适当的选项补全对话。A: Good morning, Jim!B: 1.________A: What's this?B: It's a photo of my sister.A: 2.________B: Kate.A: 3.________B: She is twenty years old.A: 4.________B: She is a music teacher.A: It's great.
