64-67 DC DA

填空题

在汽车上安装三效催化转化器,可使汽车尾气中的主要污染物(CO、NOx、碳氢化合物)进行相互反应,生成无毒物质,减少汽车尾气污染。

(1)已知:N2(g)+ O2(g)="2NO(g)" △H=+180.5 kJ/mol  

2C(s)+ O2(g)="2CO(g)" △H="-221.0" kJ/mol

C(s)+ O2(g)=CO2(g) △H="-393.5" kJ/mol

尾气转化的反应之一:2NO(g)+2CO(g)=N2(g)+2CO2(g) △H            

(2)某研究性学习小组在技术人员的指导下,在某温度时,按下列流程探究某种催化剂作用下的反应速率,用气体传感器测得不同时间的NO和CO浓度如表:

请回答下列问题(均不考虑温度变化对催化剂催化效率的影响):

①前2s内的平均反应速率v (N2) = ___________________。

②在该温度下,反应的平衡常数K =           。(只写出计算结果)

③对于该可逆反应,通过综合分析以上信息,至少可以说明     (填字母)。

A.该反应的反应物混合后很不稳定

B.该反应一旦发生将在很短的时间内完成

C.该反应体系达到平衡时至少有一种反应物的百分含量较小

D.该反应在一定条件下能自发进行

E.该反应使用催化剂意义不大

(3)CO分析仪以燃料电池为工作原理,其装置如图所示,该电池中电解质为氧化钇-氧化钠,其中O2-可以在固体介质NASICON中自由移动。下列说法错误的是     

A.负极的电极反应式为:CO+O2—―2e-=CO2

B.工作时电极b作正极,O2-由电极a流向电极b

C.工作时电子由电极a通过传感器流向电极b

D.传感器中通过的电流越大,尾气中CO的含量越高
