问答题

(16分)I、用CH4催化还原氮氧化物可以消除氮氧化物的污染。已知:

①CH4(g)+4NO2(g)=4NO(g)+ CO2(g)+2H2O(g)     △H=" -574" kJ·mol-l 

②CH4(g)+4NO(g)=2N2(g)+ CO2(g)+ 2H2O(g)       △H=" -1160" kJ·mol-l

③H2O(g)=H2O(1)    △H=-44.0 kJ·mol-l

写出CH4(g)与NO2(g)反应生成N2(g)、CO2(g)和H2O(1)的热化学方程式____   

II、开发新能源和三废处理都是可持续发展的重要方面。

(1)由碳的氧化物赢接合成乙醇燃料已进入大规模生产。如采取以CO和H2为原料合成乙醇,化学反应方程式:2CO(g)+4H2(g)-CH3CH2OH(g)+H2O(g);若密闭容器中充有10 mol CO与20mol H2,在催化剂作用下反应生成乙醇:CO的转化率(a)与温度、压强的关系如图所示。

①若A、B两点表示在某时刻达到的平衡状态,此时在A点时容器的体积为10L,则该温度下的平衡常数:K=____     

②若A、C两点都表示达到的平衡状态,则白反应开始到达平衡状态所需的时间tA    tC(填 “>”、“<”或“=”)。

(2)日前工业上也可以用CO2来生产甲醇。一定条件下发生反应:CO2(g)+3H2(g)   CH3OH(g)+H2O(g)△H<0,若将6mo1 CO2和8mol H2充入2L的密闭容器中,测得H2的物质的量随时间变化的曲线如右图所示(实线)。

①若改变某一实验条件再进行两次实验,测得H2的物质的量随时间变化如图中虚线所示,曲线I对应的实验条件改变可能是       ,曲线II对应的实验条件改变可能是____  

②请在答题卷图中绘出甲醇的物质的量随时间变化曲线。

III、用MnO2制KMnO4的工艺流程如图:电解池中两极材料均为碳棒,在水或酸性溶液中K2MnO4发生歧化而变成MnO2和KMnO4

①写出240℃熔融时发生反应的化学方程式              ,投料时必须满足n(KOH):n(MnO2              

②阳极的电极反应为                   

③B物质是          (填化学式),可以循环使用的物质是           (填化学式)。

Regardless of their political affiliation, in all countries women must overcome a host of stumbling blocks that limit their political careers. "Most obstacles to progress consist of (1) of various kinds," says the Inter-Parliamentary Union (IPU), a Geneva-based organization (2) 139 parliaments, including the lack of time, training, information, self-confidence, money, support, motivation, women’s networks and solidarity between women.

In every culture, prejudice and stereotypes (3) hard. The belief still holds (4) that women belong in the kitchen and (5) the children, not at election (6) or in the Speaker’s chair. The media often reinforce traditional images of women, who, upon entering politics, also bear the brunt (正面冲击) of verbal and physical (7) .

In impoverished (贫穷的) countries (8) by civil conflicts and deteriorating economic and social conditions, women are (9) by the tasks of managing everyday life and looking after their families.

The IPU stresses the general lack of child-care facilities—often (10) a privileged few—the (11) of political parties to change the times and running of meetings and the weak backing women receive from their families. That support, which is (12) as well as financial, is (13) vital because women have internalized (14) images of themselves since the (15) of time and often suffer from low self-confidence.

Another obstacle is the lack of financial resources, especially as election campaigns become increasingly expensive. (16) , women encounter more or less open machismo (男子汉的高傲) in the (17) of closed political circles (18) entry to the "second sex. " Lastly, they (19) the lack of solidarity between women, (20) by the fact that the number of available positions is limited.
